<v Rashid Shams>different geometric parameters
that we explored and identified</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/360-3
00:01:51.355 --> 00:01:54.717

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/394-0
00:02:06.393 --> 00:02:07.313
<v Rashid Shams>So I'll just start.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/412-0
00:02:12.313 --> 00:02:15.650
<v Rashid Shams>So the outline of the
presentation, this presentation</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/412-1
00:02:15.650 --> 00:02:17.443
<v Rashid Shams>will be in three major parts.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/429-0
00:02:17.553 --> 00:02:20.530
<v Rashid Shams>In the first part, I will
discuss the introduction and the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/429-1
00:02:20.530 --> 00:02:21.943
<v Rashid Shams>motivation behind this work.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/490-0
00:02:22.033 --> 00:02:25.560
<v Rashid Shams>The data set that we use in the
side response in Los Angeles and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/490-1
00:02:25.560 --> 00:02:29.088
<v Rashid Shams>the VS 30, the second part will
discuss the geometric parameters</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/490-2
00:02:29.088 --> 00:02:32.181
<v Rashid Shams>that we looked at and explored
for Los Angeles basin and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/490-3
00:02:32.181 --> 00:02:35.492
<v Rashid Shams>different symmetry basins and so
Cal, which will be detailed</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/490-4
00:02:35.492 --> 00:02:37.663
<v Rashid Shams>about the description of the
parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/506-0
00:02:37.673 --> 00:02:40.264
<v Rashid Shams>Our intuition behind the
parameters they use and how did</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/506-1
00:02:40.264 --> 00:02:41.583
<v Rashid Shams>we estimate those parameters?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/551-0
00:02:42.663 --> 00:02:45.863
<v Rashid Shams>The third part will go over the
model development that we did</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/551-1
00:02:45.863 --> 00:02:48.753
<v Rashid Shams>based on those geometric
parameters and the performance</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/551-2
00:02:48.753 --> 00:02:51.746
<v Rashid Shams>of the developed model in
comparison to the ground motion</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/551-3
00:02:51.746 --> 00:02:54.688
<v Rashid Shams>models and ending with key
takeaways and future scope of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/551-4
00:02:54.688 --> 00:02:55.153
<v Rashid Shams>the work.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/623-0
00:02:56.623 --> 00:03:00.453
<v Rashid Shams>So moving on, so we know the
current ground motion model that</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/623-1
00:03:00.453 --> 00:03:04.036
<v Rashid Shams>we have, they capture site
related effects in a form of a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/623-2
00:03:04.036 --> 00:03:07.989
<v Rashid Shams>site component or some kind of
site component which is based on</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/623-3
00:03:07.989 --> 00:03:11.696
<v Rashid Shams>majorly 1 dimensional site
parameters such as VS 30 or base</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/623-4
00:03:11.696 --> 00:03:14.723
<v Rashid Shams>in depth such as 0.5 or 0.5, ISO
surface depths.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/668-0
00:03:15.273 --> 00:03:18.382
<v Rashid Shams>So this approach captures most
of the site related features and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/668-1
00:03:18.382 --> 00:03:20.909
<v Rashid Shams>average size effects,
essentially based on sediment</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/668-2
00:03:20.909 --> 00:03:23.581
<v Rashid Shams>deposit, but it is limited in
capturing data and multi</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/668-3
00:03:23.581 --> 00:03:26.593
<v Rashid Shams>dimensional 2 dimensional and
three dimensional side effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/717-0
00:03:27.643 --> 00:03:31.413
<v Rashid Shams>So our major aim or overarching
aim of this work was to export</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/717-1
00:03:31.413 --> 00:03:34.585
<v Rashid Shams>geometric parameters which can
complement or work in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/717-2
00:03:34.585 --> 00:03:38.295
<v Rashid Shams>conjunction with one decided
parameters such as VS theory and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/717-3
00:03:38.295 --> 00:03:39.193
<v Rashid Shams>base in depths.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/752-0
00:03:39.723 --> 00:03:42.912
<v Rashid Shams>And we worked on this exporting
these parameters, incorporating</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/752-1
00:03:42.912 --> 00:03:45.802
<v Rashid Shams>the geometric parameters and
models in commotion model to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/752-2
00:03:45.802 --> 00:03:48.593
<v Rashid Shams>finally reduce variability and
site to site dispersion.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/766-0
00:03:49.103 --> 00:03:52.273
<v Rashid Shams>So we carried out this work in
three major steps.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/794-0
00:03:52.683 --> 00:03:56.053
<v Rashid Shams>So first step was studying the
basin and defining basin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/794-1
00:03:56.053 --> 00:03:59.364
<v Rashid Shams>sedimentary basin shape and
outline and boundary using</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/794-2
00:03:59.364 --> 00:04:02.193
<v Rashid Shams>geological cross sections and
basement depths.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/800-0
00:04:03.973 --> 00:04:05.613
<v Rashid Shams>Second step involved.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/880-0
00:04:06.413 --> 00:04:10.330
<v Rashid Shams>Uh, deriving base in geometric
parameters, exploring different</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/880-1
00:04:10.330 --> 00:04:13.874
<v Rashid Shams>parameters that could work as a
predictive parameter for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/880-2
00:04:13.874 --> 00:04:17.480
<v Rashid Shams>understanding based effects or
capturing unaccounted side</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/880-3
00:04:17.480 --> 00:04:21.459
<v Rashid Shams>effects and commotion models we
usually we mostly used basement</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/880-4
00:04:21.459 --> 00:04:25.190
<v Rashid Shams>depths and geomorphological
features for deriving different</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/880-5
00:04:25.190 --> 00:04:29.107
<v Rashid Shams>geometric parameters, and the
third is the final step involves</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/880-6
00:04:29.107 --> 00:04:32.713
<v Rashid Shams>evaluation of some selected suit
of geometric parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/906-0
00:04:32.823 --> 00:04:35.644
<v Rashid Shams>Incorporation of those
parameters in models, model</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/906-1
00:04:35.644 --> 00:04:39.073
<v Rashid Shams>development and evaluation of
the performance of the model in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/906-2
00:04:39.073 --> 00:04:41.783
<v Rashid Shams>comparison to the original
ground motion models.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/942-0
00:04:44.273 --> 00:04:47.847
<v Rashid Shams>So moving on with the data set
that we use, our data set mostly</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/942-1

00:05:01.126 --> 00:05:05.724
<v Rashid Shams>Socal data that we mostly use
and the bottom plot shows the</v>

00:05:05.724 --> 00:05:10.705
<v Rashid Shams>number of recordings with period

00:05:10.705 --> 00:05:15.533
<v Rashid Shams>is the NCVS 2 data from 2014 and
where the blue dashed line is</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1041-5
00:05:15.533 --> 00:05:20.208
<v Rashid Shams>the NJS 2 Socal data set so we
can see the Njus 2 Socal data</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1041-6
00:05:20.208 --> 00:05:24.883
<v Rashid Shams>set forms a large chunk of the
total NJBS 2 global data set.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1075-0
00:05:25.553 --> 00:05:28.881
<v Rashid Shams>We use several filters to filter
out the data, so we use only</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1075-1
00:05:28.881 --> 00:05:32.370
<v Rashid Shams>events of magnitude greater than
four magnitude distance cutoff,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1075-2
00:05:32.370 --> 00:05:35.483
<v Rashid Shams>and we only consider sites with
minimum three recordings.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1105-0
00:05:35.953 --> 00:05:41.350
<v Rashid Shams>So finally we had close to
10,000 recordings in Socal with</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1105-1
00:05:41.350 --> 00:05:45.833
<v Rashid Shams>931 sites in Socal and 182 sites
in Los Angeles.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1127-0
00:05:45.993 --> 00:05:49.848
<v Rashid Shams>Listen, so this was the data set
that we used for the analysis</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1127-1
00:05:49.848 --> 00:05:52.113
<v Rashid Shams>and looking at different
parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1158-0
00:05:53.073 --> 00:05:58.045
<v Rashid Shams>So this map shows our major
study region, which is Socal,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1158-1
00:05:58.045 --> 00:06:03.103
<v Rashid Shams>where the red colored polygons
are major SoCal sedimentary</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1158-2
00:06:03.103 --> 00:06:03.703
<v Rashid Shams>basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1169-0
00:06:03.713 --> 00:06:05.583
<v Rashid Shams>We can see loss analysis basin
in the center.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1195-0
00:06:05.593 --> 00:06:08.820
<v Rashid Shams>We have so Hangable Basin, San
Fernando Basin, close to Los</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1195-1
00:06:08.820 --> 00:06:11.724
<v Rashid Shams>Angeles Basin and all the
different color markers are</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1195-2
00:06:11.724 --> 00:06:13.123
<v Rashid Shams>different site categories.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1221-0
00:06:13.293 --> 00:06:16.812
<v Rashid Shams>So the red color markers are
basins which are basin sites or</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1221-1
00:06:16.812 --> 00:06:19.523
<v Rashid Shams>the sites which are within
sedimentary basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1238-0
00:06:19.813 --> 00:06:22.869
<v Rashid Shams>Then we have basinet sites which
are on the edge of sedimentary</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1238-1
00:06:22.869 --> 00:06:23.203
<v Rashid Shams>basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1280-0
00:06:23.653 --> 00:06:27.042
<v Rashid Shams>The inverted yellow markers are
valley size, which are smaller</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1280-1
00:06:27.042 --> 00:06:30.270
<v Rashid Shams>ways since valleys and then we
have non basin sites such as</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1280-2
00:06:30.270 --> 00:06:33.229
<v Rashid Shams>Mountain Hills which are
represented by uh white color</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1280-3
00:06:33.229 --> 00:06:34.843

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1303-0
00:06:35.313 --> 00:06:38.967
<v Rashid Shams>So we have different side

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1303-1
00:06:38.967 --> 00:06:40.163

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1361-0
00:06:50.933 --> 00:06:55.233
<v Rashid Shams>We have Palos Verdes the best,
SO and all the markers are</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1361-1
00:06:55.233 --> 00:06:58.643
<v Rashid Shams>colored by number of recordings
in the basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1391-0
00:06:58.693 --> 00:07:02.148
<v Rashid Shams>I'm only showing side stations

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1391-1
00:07:02.148 --> 00:07:05.493
<v Rashid Shams>we can see we have a bunch of

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1391-2
00:07:05.493 --> 00:07:07.083

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1422-0
00:07:09.963 --> 00:07:13.382
<v Rashid Shams>Moving on to ground motion

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1422-2
00:07:17.272 --> 00:07:20.043
<v Rashid Shams>evaluate the performance of the

<v Rashid Shams>Uh.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1445-0
00:07:22.043 --> 00:07:26.075
<v Rashid Shams>Work through and carry out
residue analysis based on the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1445-1
00:07:26.075 --> 00:07:26.783
<v Rashid Shams>and JBS 2.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1498-0
00:07:26.793 --> 00:07:30.462
<v Rashid Shams>So-called data set that I
discussed previously, so we used</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1498-1
00:07:30.462 --> 00:07:34.192
<v Rashid Shams>a bullet all 2014 ground motion

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1498-2
00:07:34.192 --> 00:07:37.923
<v Rashid Shams>Socal Basin model, the Socal
Basin model is conditioned and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1498-3
00:07:37.923 --> 00:07:41.592
<v Rashid Shams>function of V study based in
depth and the location of the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1498-4
00:07:41.592 --> 00:07:41.903
<v Rashid Shams>site.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1543-0
00:07:41.913 --> 00:07:45.539
<v Rashid Shams>So if the site is inside of base
in outside the basin for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1543-1
00:07:45.539 --> 00:07:49.416
<v Rashid Shams>different social basins based on
this ground motion model, we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1543-2
00:07:49.416 --> 00:07:53.230
<v Rashid Shams>compute a total residuals, which
is a difference between the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1543-3
00:07:53.230 --> 00:07:54.543
<v Rashid Shams>observation and data.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1584-0
00:07:55.233 --> 00:07:58.786
<v Rashid Shams>The model estimate we partition
the total residuals into event</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1584-1
00:07:58.786 --> 00:08:01.832
<v Rashid Shams>residuals and within event
residuals where we further</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1584-2
00:08:01.832 --> 00:08:05.498
<v Rashid Shams>partition within event residuals
into site residuals represented</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1584-3
00:08:05.498 --> 00:08:07.303
<v Rashid Shams>by Aris and remaining residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1603-0
00:08:08.213 --> 00:08:11.772
<v Rashid Shams>So This site is duals, are what
we are majorly concerned about</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1603-1
00:08:11.772 --> 00:08:12.563
<v Rashid Shams>in this study.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1653-0
00:08:12.613 --> 00:08:15.343
<v Rashid Shams>So the site has majorly
represents unaccounted side</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1653-1
00:08:15.343 --> 00:08:18.127
<v Rashid Shams>effects, but by the ground
motion model, so we'll be</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1653-2
00:08:18.127 --> 00:08:21.592
<v Rashid Shams>further looking at site as duals
in Los Angeles Basin and so Cal,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1653-3
00:08:21.592 --> 00:08:24.113
<v Rashid Shams>when we look at different
geometric parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1693-0
00:08:28.623 --> 00:08:33.583
<v Rashid Shams>So looking at site response and
site results in Los Angeles</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1693-1
00:08:33.583 --> 00:08:38.709
<v Rashid Shams>Basin and VS 30 so this figure
shows site as duals in lost in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1693-2
00:08:38.709 --> 00:08:40.693
<v Rashid Shams>Socal and Lawsons Basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1723-0
00:08:40.703 --> 00:08:45.833
<v Rashid Shams>So we I have site residuals
areas on Y axis and VS 30 on X</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1723-1
00:08:45.833 --> 00:08:49.833
<v Rashid Shams>axis for different period ranges
all the way.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1761-0
00:08:49.843 --> 00:08:52.766
<v Rashid Shams>Markers are Socal sites
stations, and the blue</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1761-1
00:08:52.766 --> 00:08:56.808
<v Rashid Shams>highlighted markers are for loss
and it's based on where the bin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1761-2
00:08:56.808 --> 00:09:00.353
<v Rashid Shams>means are for Los Angeles for
red and so Cal for yellow.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1785-0
00:09:00.703 --> 00:09:03.913
<v Rashid Shams>So by looking at these site,
results are computed after</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1785-1
00:09:03.913 --> 00:09:06.263
<v Rashid Shams>incorporating the basin model
for Socal.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1795-0
00:09:06.353 --> 00:09:07.963
<v Rashid Shams>So we can still look at that.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1814-0
00:09:07.973 --> 00:09:10.887
<v Rashid Shams>There are some strains, some
trends inside residuals at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1814-1
00:09:10.887 --> 00:09:13.593
<v Rashid Shams>longer periods, and there is a
considerable spread.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1840-0
00:09:14.653 --> 00:09:17.723
<v Rashid Shams>So even though we study is doing
a good job, it's capturing</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1840-1
00:09:17.723 --> 00:09:20.537
<v Rashid Shams>average side effects and
subsurface rated side effects</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1840-2
00:09:20.537 --> 00:09:21.663
<v Rashid Shams>and basically effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1873-0
00:09:21.953 --> 00:09:24.407
<v Rashid Shams>But there is still some
unaccounted side effects related</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1873-1
00:09:24.407 --> 00:09:27.248
<v Rashid Shams>to two dimensional 3 dimensional
features and phenomena happening</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1873-2
00:09:27.248 --> 00:09:29.874
<v Rashid Shams>beneath the site which still
needs to be captured and looked</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1873-3
00:09:29.874 --> 00:09:30.003
<v Rashid Shams>at.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1921-0
00:09:30.053 --> 00:09:33.426
<v Rashid Shams>So if we zoom in and look only
for so only at Los Angeles</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1921-1
00:09:33.426 --> 00:09:36.798
<v Rashid Shams>Basin, this figure shows size
only lossless basin and the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1921-2
00:09:36.798 --> 00:09:40.287
<v Rashid Shams>yellow color markers are bin
means we again looking at site</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1921-3
00:09:40.287 --> 00:09:41.683
<v Rashid Shams>test duals with V study.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1953-0
00:09:41.833 --> 00:09:44.613
<v Rashid Shams>So we can see as we move to
longer periods, there is a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1953-1
00:09:44.613 --> 00:09:47.545
<v Rashid Shams>positive trend at higher VS 30
values and there is a some</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/1953-2
00:09:47.545 --> 00:09:48.303
<v Rashid Shams>spread as well.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2021-0
00:09:49.333 --> 00:09:52.239
<v Rashid Shams>So to summarize that, even
though the story is going a good</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2021-1
00:09:52.239 --> 00:09:55.241
<v Rashid Shams>job in capturing basin effects
and side effects, but there is</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2021-2
00:09:55.241 --> 00:09:58.244
<v Rashid Shams>still some bias there is related
to two dimensional and three</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2021-3
00:09:58.244 --> 00:10:01.004
<v Rashid Shams>dimensional side effects not
being captured by these one</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2021-4
00:10:01.004 --> 00:10:03.765
<v Rashid Shams>dimensional side parameters
which motivates us to export</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2021-5
00:10:03.765 --> 00:10:06.332
<v Rashid Shams>some further additional
parameters which leads us to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2021-6
00:10:06.332 --> 00:10:07.833
<v Rashid Shams>exploring geometric parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2069-0
00:10:09.783 --> 00:10:12.822
<v Rashid Shams>So before moving on to looking
at geometric parameters,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2069-1
00:10:12.822 --> 00:10:16.078
<v Rashid Shams>understanding and defining
geometric parameters involves we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2069-2
00:10:16.078 --> 00:10:19.062
<v Rashid Shams>have to define some kind of
boundary for the basis and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2069-3
00:10:19.062 --> 00:10:21.993
<v Rashid Shams>basement constraints which forms
an integral part of.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2092-0
00:10:22.043 --> 00:10:25.577
<v Rashid Shams>When we look at basins and we'll
use this basement constraints</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2092-1
00:10:25.577 --> 00:10:28.943
<v Rashid Shams>and basement depths in defining
these geometric parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2115-0
00:10:30.473 --> 00:10:33.914
<v Rashid Shams>So we start with looking at
crystalline basement basement</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2115-1
00:10:33.914 --> 00:10:36.643
<v Rashid Shams>basement which we adopted from
CMH community.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2122-0
00:10:36.653 --> 00:10:38.643
<v Rashid Shams>Will upstream model show at all
2015?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2134-0
00:10:38.993 --> 00:10:42.443
<v Rashid Shams>So the map here shows specially
variation of C image.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2153-0
00:10:42.453 --> 00:10:48.265
<v Rashid Shams>The red color boundaries for Los
Angeles based in and we can see</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2153-1
00:10:48.265 --> 00:10:50.143
<v Rashid Shams>the uh, the basement.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2187-0
00:10:50.513 --> 00:10:53.680
<v Rashid Shams>The Christian basement gets
deeper as we move towards the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2187-1
00:10:53.680 --> 00:10:57.065
<v Rashid Shams>center of the basin and gets
shallower as we move towards the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2187-2
00:10:57.065 --> 00:10:58.103
<v Rashid Shams>edge of the basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2219-0
00:10:58.673 --> 00:11:02.315
<v Rashid Shams>And this Christian basement is
actually the depth of the basin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2219-1
00:11:02.315 --> 00:11:05.206
<v Rashid Shams>where transitioning from
sedimentary rocks to the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2219-2
00:11:05.206 --> 00:11:07.923
<v Rashid Shams>crystalline uh Christine rocks
and hard rocks.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2221-0
00:11:08.733 --> 00:11:09.353
<v Rashid Shams>So this.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2253-0
00:11:11.353 --> 00:11:15.385
<v Rashid Shams>This motivates us to look into a
sedimentary basement depth which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2253-1
00:11:15.385 --> 00:11:18.623
<v Rashid Shams>will be more of an actual base
basement for a basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2265-0
00:11:18.633 --> 00:11:22.351
<v Rashid Shams>Will will transition from hard
or stiff soil to sedimentary</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2265-1
00:11:22.351 --> 00:11:22.723
<v Rashid Shams>rocks.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2292-0
00:11:23.093 --> 00:11:26.294
<v Rashid Shams>So for this we look at different
cross sections Geological cross</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2292-1
00:11:26.294 --> 00:11:27.723
<v Rashid Shams>section cross and this basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2314-0
00:11:27.813 --> 00:11:31.979
<v Rashid Shams>We looked at multiple cross
sections and I'll be showing two</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2314-1
00:11:31.979 --> 00:11:35.803
<v Rashid Shams>major cross sections highlighted
in red in this figure.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2355-0
00:11:36.473 --> 00:11:39.264
<v Rashid Shams>So the first possession that
we'll look at is B that is</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2355-1
00:11:39.264 --> 00:11:42.305
<v Rashid Shams>transacting across starting from
Palace, today's transacting</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2355-2
00:11:42.305 --> 00:11:45.495
<v Rashid Shams>across the central part of the
basin and moving towards the San</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2355-3
00:11:45.495 --> 00:11:46.193
<v Rashid Shams>Gabriel Basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2386-0
00:11:48.563 --> 00:11:53.415
<v Rashid Shams>So this figure on the top shows
Geological Cross section and the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2386-1
00:11:53.415 --> 00:11:57.894
<v Rashid Shams>figure on the bottom uh shows
the velocity profile from CMD</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2386-2
00:11:57.894 --> 00:12:00.283
<v Rashid Shams>match up to 15 kilometers depth.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2423-0
00:12:02.223 --> 00:12:06.059
<v Rashid Shams>And we can see that the Trop
geologic official shows the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2423-1
00:12:06.059 --> 00:12:10.232
<v Rashid Shams>bottom part shows the transition
from MU scene and older mule</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2423-2
00:12:10.232 --> 00:12:14.203
<v Rashid Shams>scene to basement complex and
the bottom velocity profile.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2446-0
00:12:14.213 --> 00:12:17.296
<v Rashid Shams>The black solid black line is
the ZCB, which is the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2446-1
00:12:17.296 --> 00:12:20.973
<v Rashid Shams>crystalline basement that we
looked at in the previous slide.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2481-0
00:12:22.003 --> 00:12:26.866
<v Rashid Shams>So this alliance with the museen
and above musine and medium and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2481-1
00:12:26.866 --> 00:12:31.505
<v Rashid Shams>older music boundary transition
from the centimeter rocks and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2481-2
00:12:31.505 --> 00:12:34.723
<v Rashid Shams>rocks through the piston
basement complex.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2542-0
00:12:36.893 --> 00:12:41.230
<v Rashid Shams>And in the gospel defining a
sedimentary basement, we look at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2542-1
00:12:41.230 --> 00:12:45.498
<v Rashid Shams>a lower piercing and transition
from lower to upper Miocene,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2542-2
00:12:45.498 --> 00:12:49.836
<v Rashid Shams>which is more of a transition
from stiffer soils to more of a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2542-3
00:12:49.836 --> 00:12:53.894
<v Rashid Shams>sedimentary rocks instead of a
crystalline basement which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2542-4
00:12:53.894 --> 00:12:55.153
<v Rashid Shams>corresponds to uh.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2545-0
00:12:55.493 --> 00:12:55.923
<v Rashid Shams>When when?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2564-0
00:12:55.933 --> 00:13:00.743
<v Rashid Shams>5 to 2.5 kilometer per second
somewhere in this velocity cross</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2564-1
00:13:00.743 --> 00:13:02.423
<v Rashid Shams>section above the ZCB.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2582-0
00:13:02.873 --> 00:13:07.904
<v Rashid Shams>When we look at the second
velocity cross second Geological</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2582-1
00:13:07.904 --> 00:13:10.923
<v Rashid Shams>Cross section which is E dash
here.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2607-0
00:13:10.973 --> 00:13:15.046
<v Rashid Shams>So we'll be looking at ABC and D
parts of this cross section,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2607-1
00:13:15.046 --> 00:13:19.120
<v Rashid Shams>which again transects across the
basin and starts from Palace</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2607-2
00:13:19.120 --> 00:13:19.843
<v Rashid Shams>Verdes, so.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2642-0
00:13:21.903 --> 00:13:25.129
<v Rashid Shams>This is the cross section, so
the top plot again shows the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2642-1
00:13:25.129 --> 00:13:28.464
<v Rashid Shams>Geological Cross section and
bottom plot is for the velocity</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2642-2
00:13:28.464 --> 00:13:30.323
<v Rashid Shams>profile up to 15 kilometer
depth.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2656-0
00:13:31.933 --> 00:13:34.867
<v Rashid Shams>Where again, the solid black
line is for ZCB crystal basement</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2656-1
00:13:34.867 --> 00:13:35.293
<v Rashid Shams>boundary.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2692-0
00:13:37.123 --> 00:13:40.757
<v Rashid Shams>So in this cross section we can
see that there is a transition</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2692-1
00:13:40.757 --> 00:13:44.161
<v Rashid Shams>from Fernando formation or
Repetto to reformation which is</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2692-2
00:13:44.161 --> 00:13:46.353
<v Rashid Shams>from Pliocene epoch to Miocene
epoch.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2726-0
00:13:48.133 --> 00:13:51.679
<v Rashid Shams>So this transition is the
transition that we're looking</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2726-1
00:13:51.679 --> 00:13:55.733
<v Rashid Shams>for for establishing the crystal
sedimentary basement boundary,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2726-2
00:13:55.733 --> 00:13:59.343
<v Rashid Shams>which again aligns with 1.5 to
2.5 kilometer per second.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2764-0
00:13:59.353 --> 00:14:02.563
<v Rashid Shams>So we conclude on looking at 1.5
kilometer per second and 2.3</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2764-1
00:14:02.563 --> 00:14:05.618
<v Rashid Shams>kilometers per second 1.5
kilometer per second has already</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2764-2
00:14:05.618 --> 00:14:07.223
<v Rashid Shams>been used in one motion models.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2781-0
00:14:07.233 --> 00:14:10.925
<v Rashid Shams>As I surface depth and we look
at 2.3 kilometer per second as</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2781-1
00:14:10.925 --> 00:14:11.223
<v Rashid Shams>well.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2799-0
00:14:11.653 --> 00:14:15.528
<v Rashid Shams>So moving on, we look at the
depth to Kristen to the basement</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2799-1
00:14:15.528 --> 00:14:16.403
<v Rashid Shams>for the basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2841-0
00:14:16.413 --> 00:14:20.274
<v Rashid Shams>So and the plot on the right
plot on the left shows Kristen</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2841-1
00:14:20.274 --> 00:14:23.685
<v Rashid Shams>basement depth with site
residuals on Y axis and ZCB</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2841-2
00:14:23.685 --> 00:14:25.873
<v Rashid Shams>Christian basement dev on X
axis.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2899-0
00:14:26.853 --> 00:14:30.891
<v Rashid Shams>Stop markers are for social
sites and they are colored by</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2899-1
00:14:30.891 --> 00:14:34.929
<v Rashid Shams>different site categories such
as Basin, Mountain, Hills,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2899-2
00:14:34.929 --> 00:14:39.385
<v Rashid Shams>Valley and basin edges, and the
plot on the right is again site</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2899-3
00:14:39.385 --> 00:14:43.075
<v Rashid Shams>as duals in Socal plotted with
GCB, 2.3 which is the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2899-4
00:14:43.075 --> 00:14:45.233
<v Rashid Shams>sedimentary basement depth ZSB.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2914-0
00:14:45.763 --> 00:14:48.879
<v Rashid Shams>So we again look at different
point markers colored by</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2914-1
00:14:48.879 --> 00:14:50.353
<v Rashid Shams>different site categories.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2929-0
00:14:50.363 --> 00:14:55.643
<v Rashid Shams>So in general, we don't see a
specific trend or significant</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2929-1
00:14:55.643 --> 00:14:56.083
<v Rashid Shams>bias.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2970-0
00:14:57.413 --> 00:15:01.069
<v Rashid Shams>We suggest that uh, these
basement depths, although are</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2970-1
00:15:01.069 --> 00:15:04.920
<v Rashid Shams>important for helping us in
estimating different geometric</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2970-2
00:15:04.920 --> 00:15:08.381
<v Rashid Shams>parameters, but they don't
themselves don't have any</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/2970-3
00:15:08.381 --> 00:15:12.363
<v Rashid Shams>relative power in capturing any
additional side effects. Uh.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3014-0
00:15:14.173 --> 00:15:16.732
<v Rashid Shams>So as we don't observe any
significant bias and trends</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3014-1
00:15:16.732 --> 00:15:19.477
<v Rashid Shams>inside as well with these
basement depths, which indicates</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3014-2
00:15:19.477 --> 00:15:22.082
<v Rashid Shams>that only isosurface depths are
not enough to capture 2</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3014-3
00:15:22.082 --> 00:15:23.943
<v Rashid Shams>dimensional 3 dimensional side
effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3043-0
00:15:23.953 --> 00:15:27.915
<v Rashid Shams>Because so this motivates us
again to look at some other</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3043-1
00:15:27.915 --> 00:15:32.155
<v Rashid Shams>geometric parameters, although
we'll be using these basement</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3043-2
00:15:32.155 --> 00:15:33.823
<v Rashid Shams>depths and the boundary.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3066-0
00:15:33.873 --> 00:15:37.981
<v Rashid Shams>Uh basin constraints that we
looked at in, in computing those</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3066-1
00:15:37.981 --> 00:15:40.433
<v Rashid Shams>dramatic parameters that we look
at.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3122-0
00:15:41.263 --> 00:15:44.855
<v Rashid Shams>So this brings us to the second
part of the presentation, which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3122-1
00:15:44.855 --> 00:15:48.167
<v Rashid Shams>involves discussing different
geometric parameters that we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3122-2
00:15:48.167 --> 00:15:51.254
<v Rashid Shams>looked at and how did we assess
the performance of the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3122-3
00:15:51.254 --> 00:15:54.229
<v Rashid Shams>parameters against the site,
test duals in capturing</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3122-4
00:15:54.229 --> 00:15:57.316
<v Rashid Shams>unaccounted side effects and
basin related effects for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3122-5
00:15:57.316 --> 00:15:58.383
<v Rashid Shams>sedimentary basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3143-0
00:16:00.223 --> 00:16:03.670
<v Rashid Shams>So the first parameter that we
looked at is standard deviation</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3143-1
00:16:03.670 --> 00:16:04.053
<v Rashid Shams>of ZCB.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3166-0
00:16:04.063 --> 00:16:07.769
<v Rashid Shams>So ZCB again is the crystalline
basement depth that we looked at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3166-1
00:16:07.769 --> 00:16:09.993
<v Rashid Shams>in the first part of the
presentation.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3193-0
00:16:10.483 --> 00:16:14.098
<v Rashid Shams>The standard deviation we
calculate stand deviation using</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3193-1
00:16:14.098 --> 00:16:17.526
<v Rashid Shams>ZCB and the map here shows
especially variation of the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3193-2
00:16:17.526 --> 00:16:19.833
<v Rashid Shams>standard deviation of TCP
parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3226-0
00:16:20.023 --> 00:16:24.376
<v Rashid Shams>So this parameter is calculated
using a circular window or 2425</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3226-1
00:16:24.376 --> 00:16:28.525
<v Rashid Shams>hundred meters radius and we
take the stand deviation of all</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3226-2
00:16:28.525 --> 00:16:29.273
<v Rashid Shams>the points.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3243-0
00:16:29.363 --> 00:16:30.933
<v Rashid Shams>All the grid points inside the
roster.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3315-0
00:16:30.943 --> 00:16:34.305
<v Rashid Shams>We used 200 meter spacing grid
points and we take the stand</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3315-1
00:16:34.305 --> 00:16:37.668
<v Rashid Shams>deviation of all those points at
the center of the circular</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3315-2
00:16:37.668 --> 00:16:41.367
<v Rashid Shams>window and we move this circular
window to all the grid points in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3315-3
00:16:41.367 --> 00:16:44.561
<v Rashid Shams>the raster which are against
base at 200 meters and this</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3315-4
00:16:44.561 --> 00:16:47.812
<v Rashid Shams>helps us to get the stand
deviation of ZCB values at each</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3315-5
00:16:47.812 --> 00:16:49.213
<v Rashid Shams>grid point in the roster.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3327-0
00:16:49.823 --> 00:16:53.082
<v Rashid Shams>This standard deviation is like
a geological proxy for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3327-1
00:16:53.082 --> 00:16:54.563
<v Rashid Shams>subsurface heterogeneity.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3363-0
00:16:54.573 --> 00:16:58.086
<v Rashid Shams>Add pistol basement depth
because if you if we observe</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3363-1
00:16:58.086 --> 00:17:01.854
<v Rashid Shams>this raster we can see the high
standard deviation phrases</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3363-2
00:17:01.854 --> 00:17:05.367
<v Rashid Shams>correspond to faults and
geological discontinuities at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3363-3
00:17:05.367 --> 00:17:07.283
<v Rashid Shams>the basement subsurface level.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3414-0
00:17:07.793 --> 00:17:10.763
<v Rashid Shams>So this also helps us to
understand the shape of the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3414-1
00:17:10.763 --> 00:17:14.125
<v Rashid Shams>basin and basin boundary in
particular such As for loss and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3414-2
00:17:14.125 --> 00:17:17.376
<v Rashid Shams>the basin, which is a fault
bounded basin, we can see the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3414-3
00:17:17.376 --> 00:17:20.570
<v Rashid Shams>high standard division traces
corresponding to the Santa</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3414-4
00:17:20.570 --> 00:17:22.083
<v Rashid Shams>Monica and Hollywood Fault.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3439-0
00:17:23.013 --> 00:17:26.841
<v Rashid Shams>We also have a highest and
division traces for the ELISION</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3439-1
00:17:26.841 --> 00:17:30.474
<v Rashid Shams>park and point to his fault and
Newport Inglewood fault</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3439-2
00:17:30.474 --> 00:17:31.253
<v Rashid Shams>transacting.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3448-0
00:17:31.913 --> 00:17:34.113
<v Rashid Shams>Uh, across the center of the
basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3468-0
00:17:34.563 --> 00:17:37.439
<v Rashid Shams>So this helps us to get an idea
of the shape of the basins and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3468-1
00:17:37.439 --> 00:17:38.443
<v Rashid Shams>surface heterogeneity.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3489-0
00:17:40.333 --> 00:17:43.743
<v Rashid Shams>And we use focal statistics
tools and RJ is to come.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3535-0
00:17:43.873 --> 00:17:48.219
<v Rashid Shams>You compute this parameter so to
look at this parameter which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3535-1
00:17:48.219 --> 00:17:52.776
<v Rashid Shams>site as well we again plot site
as duals in Los Angeles basin on</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3535-2
00:17:52.776 --> 00:17:57.263
<v Rashid Shams>Y axis with the parameter that
is 10 division of GCB on X axis.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3568-0
00:17:57.533 --> 00:18:01.292
<v Rashid Shams>Yellow color markers have been
means so all these points are in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3568-1
00:18:01.292 --> 00:18:04.875
<v Rashid Shams>Los Angeles Basin and we can see
there is some spread inside</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3568-2
00:18:04.875 --> 00:18:05.463
<v Rashid Shams>residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3591-0
00:18:05.713 --> 00:18:09.186
<v Rashid Shams>But as you move from shorter
periods to longer periods, we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3591-1
00:18:09.186 --> 00:18:12.483
<v Rashid Shams>can see there is a there is a
trend, uh positive trend.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3594-0
00:18:12.853 --> 00:18:13.313
<v Rashid Shams>Uh.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3635-0
00:18:13.933 --> 00:18:18.055
<v Rashid Shams>Going down downwards at highest
N deviation of CB values, which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3635-1
00:18:18.055 --> 00:18:21.597
<v Rashid Shams>corresponds to higher
syndication values correspond to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3635-2
00:18:21.597 --> 00:18:25.268
<v Rashid Shams>heterogeneity or some kind of
variability in sub surface</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3635-3
00:18:25.268 --> 00:18:26.363
<v Rashid Shams>subsurface level.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3649-0
00:18:26.733 --> 00:18:30.262
<v Rashid Shams>So this parameter shows some
promise in capturing some</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3649-1
00:18:30.262 --> 00:18:32.573
<v Rashid Shams>unaccounted side effects in
basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3666-0
00:18:35.103 --> 00:18:37.921
<v Rashid Shams>We move on to another parameter
that we initially looked at,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3666-1
00:18:37.921 --> 00:18:39.123
<v Rashid Shams>which was surface texture.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3672-0
00:18:39.133 --> 00:18:41.343
<v Rashid Shams>This is another geomorphological
metric.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3714-0
00:18:41.773 --> 00:18:44.834
<v Rashid Shams>This is just the standard
deviation of surface slope, so</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3714-1
00:18:44.834 --> 00:18:48.378
<v Rashid Shams>this also helps us to understand
horizontal surficial variability</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3714-2
00:18:48.378 --> 00:18:51.492

00:19:00.756 --> 00:19:04.162
<v Rashid Shams>this parameter showed helped and

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3774-2
00:19:04.162 --> 00:19:06.823
<v Rashid Shams>good classifier for basic and

00:19:19.074 --> 00:19:21.689
<v Rashid Shams>we have San Gabriel here and we

00:19:21.689 --> 00:19:23.433
<v Rashid Shams>mountain hills and non basin

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3852-0
00:19:23.793 --> 00:19:26.886
<v Rashid Shams>This parameter help like worked
as a good classifier for basins</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3852-1
00:19:26.886 --> 00:19:27.563
<v Rashid Shams>and non basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3893-0
00:19:28.583 --> 00:19:32.481
<v Rashid Shams>Although when we look at site as

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3893-1
00:19:32.481 --> 00:19:36.797
<v Rashid Shams>representation of unaccounted

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3893-2
00:19:36.797 --> 00:19:41.182
<v Rashid Shams>we don't see any specific trend
even at longer periods and the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3893-3
00:19:41.182 --> 00:19:42.783
<v Rashid Shams>bias is also very less.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3919-0
00:19:43.253 --> 00:19:47.299
<v Rashid Shams>So this disregards any ability

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3919-1
00:19:47.299 --> 00:19:50.713
<v Rashid Shams>any 2 dimensional and three

00:19:51.993 --> 00:19:55.281
<v Rashid Shams>Although this worked as a good

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3947-1
00:19:55.281 --> 00:19:58.313
<v Rashid Shams>basins, we move on and look at
distance from basin margin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3973-0
00:19:58.463 --> 00:20:01.880
<v Rashid Shams>So distance from basin margin is
just the distance distance of a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3973-1
00:20:01.880 --> 00:20:04.877
<v Rashid Shams>site from the boundary of the

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3998-0
00:20:06.583 --> 00:20:10.078
<v Rashid Shams>So we'll again looking at site
as duals with distance for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/3998-1
00:20:10.078 --> 00:20:13.573
<v Rashid Shams>basement margin parameter, which
is X axis in kilometers.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4041-0
00:20:14.003 --> 00:20:18.034
<v Rashid Shams>So all the blue markers are
loosely based on sides and there</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4041-1
00:20:18.034 --> 00:20:22.131
<v Rashid Shams>are some red markers which are
based in edge sites defined by</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4041-2
00:20:22.131 --> 00:20:24.973
<v Rashid Shams>wiki Roll 2022 based on visual

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4068-0
00:20:26.573 --> 00:20:30.009
<v Rashid Shams>So we can see there is a break
in trend if we start from</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4068-1
00:20:30.009 --> 00:20:33.083
<v Rashid Shams>looking at shorter periods such

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4084-0
00:20:33.093 --> 00:20:36.223
<v Rashid Shams>So there is a break in trend
after 2 kilometers.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4099-0
00:20:37.013 --> 00:20:41.883
<v Rashid Shams>This trend breaking trend or

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4099-1
00:20:41.883 --> 00:20:43.143
<v Rashid Shams>longer periods.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4135-0
00:20:43.313 --> 00:20:47.078
<v Rashid Shams>So the further investigate this
big in trend, we look at this</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4135-1
00:20:47.078 --> 00:20:50.844
<v Rashid Shams>plot where I'm again showing

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4135-2
00:20:50.844 --> 00:20:52.423
<v Rashid Shams>based on margin on X axis.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4179-0
00:20:52.433 --> 00:20:56.665
<v Rashid Shams>And I have a vertical dashed

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4179-1
00:20:56.665 --> 00:21:00.755
<v Rashid Shams>all the markers beyond two

00:21:04.846 --> 00:21:08.443
<v Rashid Shams>kilometers from basin boundary
are colored in red.</v>

00:21:08.733 --> 00:21:12.694
<v Rashid Shams>So we can see if we observe the

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4223-1
00:21:12.694 --> 00:21:16.531
<v Rashid Shams>observe there is a slight break

00:21:20.873 --> 00:21:24.385
<v Rashid Shams>So we can observe that there is
a change in site response in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4269-1
00:21:24.385 --> 00:21:27.610
<v Rashid Shams>site which are closer to the

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4269-2
00:21:27.610 --> 00:21:30.949
<v Rashid Shams>present to the site which are

00:21:32.183 --> 00:21:36.213
<v Rashid Shams>And we expected some change in
this side response because Basin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4324-1
00:21:36.213 --> 00:21:40.054

00:21:40.054 --> 00:21:44.147
<v Rashid Shams>based related phenomena such as

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4324-3
00:21:44.147 --> 00:21:47.359
<v Rashid Shams>body up to surface wave

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4344-0
00:21:50.223 --> 00:21:52.861
<v Rashid Shams>So this helps us to set a

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4344-1
00:21:52.861 --> 00:21:54.423

00:22:05.183 --> 00:22:08.001
<v Rashid Shams>Although these two kilometre
margin or threshold will work</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4397-1
00:22:08.001 --> 00:22:10.819
<v Rashid Shams>only for Los Angeles Basin and
it will change depending on</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4397-2
00:22:10.819 --> 00:22:12.013
<v Rashid Shams>different types of basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4423-0
00:22:12.243 --> 00:22:15.295
<v Rashid Shams>So it might be different for

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4423-1
00:22:15.295 --> 00:22:18.293
<v Rashid Shams>depending upon the geological

00:22:23.093 --> 00:22:27.193
<v Rashid Shams>Moving on, there was another set

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4456-1
00:22:27.193 --> 00:22:31.167
<v Rashid Shams>and we turned we categorize it
under spatial area of influence</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4456-2
00:22:31.167 --> 00:22:32.303
<v Rashid Shams>for site response.</v>

00:22:33.033 --> 00:22:36.548
<v Rashid Shams>So we know that corresponds at a

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4506-1
00:22:36.548 --> 00:22:39.568
<v Rashid Shams>by site specific surface

00:22:39.568 --> 00:22:42.314
<v Rashid Shams>well as subsurface

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4506-3
00:22:42.314 --> 00:22:45.719
<v Rashid Shams>set aside, which involves soil

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4506-4
00:22:45.719 --> 00:22:46.323
<v Rashid Shams>properties.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4509-0
00:22:46.813 --> 00:22:49.303
<v Rashid Shams>But horizontal neutrality?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4541-0
00:22:49.313 --> 00:22:52.209
<v Rashid Shams>As a site has not been looked at
in detail in combination,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4541-1
00:22:52.209 --> 00:22:55.154
<v Rashid Shams>because ideally site is sponse
should be a function of both</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4541-2
00:22:55.154 --> 00:22:56.823
<v Rashid Shams>later and horizontal

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4577-0
00:22:57.253 --> 00:23:00.046
<v Rashid Shams>So our hypothesis is that the
area of influence around the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4577-1
00:23:00.046 --> 00:23:03.075
<v Rashid Shams>site that could influence site

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4577-2
00:23:03.075 --> 00:23:05.963
<v Rashid Shams>should be a function of both
vertical and later variability.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4607-0
00:23:06.673 --> 00:23:09.774
<v Rashid Shams>So we're little variability
could be a function of some kind</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4607-1
00:23:09.774 --> 00:23:12.672
<v Rashid Shams>of versioning variability in

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4607-2
00:23:12.672 --> 00:23:13.943
<v Rashid Shams>roughness of the surface.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4626-0
00:23:15.073 --> 00:23:18.130
<v Rashid Shams>While vertical variability will
be a function of soil</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4626-1
00:23:18.130 --> 00:23:21.583
<v Rashid Shams>properties, she have a velocity

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4644-0
00:23:22.313 --> 00:23:26.549
<v Rashid Shams>So we look at 2 parameters

00:23:27.493 --> 00:23:32.607
<v Rashid Shams>The first parameter Sai average,
we compute it as the average of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4675-1
00:23:32.607 --> 00:23:37.486
<v Rashid Shams>surface section and standard

00:23:38.593 --> 00:23:42.242
<v Rashid Shams>So surface texture is accounting
for that horizontal variability</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4713-1
00:23:42.242 --> 00:23:45.442
<v Rashid Shams>and stand deviation of V slope
between ZCB, which is the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4713-2
00:23:45.442 --> 00:23:48.698
<v Rashid Shams>crystal basement depth and Z 1.5
which is the sedimentary</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4713-3
00:23:48.698 --> 00:23:49.203
<v Rashid Shams>basement.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4792-0
00:23:49.213 --> 00:23:52.998
<v Rashid Shams>Depth is, in a sense, accounting
for that vertical variability,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4792-1
00:23:52.998 --> 00:23:56.723
<v Rashid Shams>although we are squashing that
vertical availability by taking</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4792-2
00:23:56.723 --> 00:24:00.271
<v Rashid Shams>standard deviation to the figure

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4792-3
00:24:00.271 --> 00:24:03.997
<v Rashid Shams>horizontal variability on the

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4792-4
00:24:03.997 --> 00:24:07.368
<v Rashid Shams>accounting in terms of surface
texture that we looked at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4792-5
00:24:07.368 --> 00:24:11.153
<v Rashid Shams>earlier and vertical variability
which we have squashing, which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4792-6
00:24:11.153 --> 00:24:13.873
<v Rashid Shams>is in terms of V slope between
ZCB and Z 1.5.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4840-0
00:24:13.883 --> 00:24:17.543
<v Rashid Shams>But we are squashing that by
taking the standard deviation of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4840-1
00:24:17.543 --> 00:24:21.204
<v Rashid Shams>the parameter of this parameter,
and we are averaging both of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4840-2
00:24:21.204 --> 00:24:24.569
<v Rashid Shams>them to get an average uh
parameter, which is a function</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4840-3
00:24:24.569 --> 00:24:26.813
<v Rashid Shams>of both lateral vertical
variability.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4877-0
00:24:27.303 --> 00:24:30.931
<v Rashid Shams>We look at another parameter in
which is a similar parameter to,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4877-1
00:24:30.931 --> 00:24:34.169
<v Rashid Shams>say average we term is an SSIS
30 which is the average of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4877-2
00:24:34.169 --> 00:24:37.183
<v Rashid Shams>against service texture and
stand deviation of VS 30.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4909-0
00:24:38.563 --> 00:24:41.979
<v Rashid Shams>So higher special area of
average parameter value should</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4909-1
00:24:41.979 --> 00:24:45.634
<v Rashid Shams>indicate more heterogeneity of
variability data side because</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4909-2
00:24:45.634 --> 00:24:46.593
<v Rashid Shams>they're average.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4923-0
00:24:46.603 --> 00:24:51.424
<v Rashid Shams>We are averaging both surface
texture and the vertical</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4923-1
00:24:51.424 --> 00:24:53.353
<v Rashid Shams>variability component.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4943-0
00:24:54.163 --> 00:24:57.157
<v Rashid Shams>So when we further investigate
the trends of these parameter,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4943-1
00:24:57.157 --> 00:24:59.233
<v Rashid Shams>which site residuals in Los
Angeles basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/4950-0
00:24:59.393 --> 00:25:00.923
<v Rashid Shams>So first we look at SCI average.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5014-0
00:25:01.763 --> 00:25:06.163
<v Rashid Shams>So all the markers for sites in
Los Angeles Basin and we have</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5014-1
00:25:06.163 --> 00:25:10.776
<v Rashid Shams>the parameter on the X axis and
situs duals in Los Angeles based</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5014-2
00:25:10.776 --> 00:25:14.892
<v Rashid Shams>on Y axis, the yellow blue
markers have been means and we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5014-3
00:25:14.892 --> 00:25:19.505
<v Rashid Shams>can see as we move to higher STI
average values, we see more red</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5014-4
00:25:19.505 --> 00:25:20.073
<v Rashid Shams>markers.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5051-0
00:25:20.343 --> 00:25:23.658
<v Rashid Shams>These red markers are the basin
stations that we defined while</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5051-1
00:25:23.658 --> 00:25:26.921
<v Rashid Shams>we looked at basin margin sites
and we set up a threshold for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5051-2
00:25:26.921 --> 00:25:28.553
<v Rashid Shams>loss and business 2 kilometers.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-0
00:25:28.843 --> 00:25:32.931
<v Rashid Shams>So all these sites are business
stations which are within 2</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-1
00:25:32.931 --> 00:25:37.360
<v Rashid Shams>kilometers from basin margin and
we consistently see at all four</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-2
00:25:37.360 --> 00:25:41.517
<v Rashid Shams>periods that these basin edge
stations are present at higher</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-3
00:25:41.517 --> 00:25:45.605
<v Rashid Shams>average values, more permanently
at greater than 1S average</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-4
00:25:45.605 --> 00:25:49.966
<v Rashid Shams>values, which kind of validates
what we hypothesize that higher</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-5
00:25:49.966 --> 00:25:53.373
<v Rashid Shams>essay values should indicate
more variability and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-6
00:25:53.373 --> 00:25:57.530
<v Rashid Shams>heterogeneity, which in sense
corresponds to basin edge size</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-7
00:25:57.530 --> 00:26:01.210
<v Rashid Shams>because they are at the basin
edge and they have more</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-8
00:26:01.210 --> 00:26:05.503
<v Rashid Shams>heterogeneity and variability in
comparison to sites which are</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5174-9
00:26:05.503 --> 00:26:09.523
<v Rashid Shams>actually in the basin or close
to the center of the basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5203-0
00:26:09.853 --> 00:26:13.136
<v Rashid Shams>So this parameter also showed
some promise to help us</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5203-1
00:26:13.136 --> 00:26:16.724
<v Rashid Shams>differentiate Basin and basin
margin sites, which could be</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5203-2
00:26:16.724 --> 00:26:19.643
<v Rashid Shams>helpful in understanding based
in edge effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5218-0
00:26:19.993 --> 00:26:22.683
<v Rashid Shams>So this parameter is also could
also complement based in.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5236-0
00:26:23.303 --> 00:26:25.821
<v Rashid Shams>This is from basin margin
parameter in identifying basin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5236-1
00:26:25.821 --> 00:26:26.263
<v Rashid Shams>edge size.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5263-0
00:26:27.673 --> 00:26:31.300
<v Rashid Shams>Moving on, looking at the second
parameter, which is SAIS theory,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5263-1
00:26:31.300 --> 00:26:34.818
<v Rashid Shams>which was the average of surface
texture and standard deviation</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5263-2
00:26:34.818 --> 00:26:35.423
<v Rashid Shams>of VSTS 30.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5298-0
00:26:36.133 --> 00:26:39.678
<v Rashid Shams>So we again look at all the
sites in Socal which is in Gray</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5298-1
00:26:39.678 --> 00:26:43.283
<v Rashid Shams>and we have highlighted the loss
in the basin sides in blue.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5363-0
00:26:43.793 --> 00:26:46.946
<v Rashid Shams>So we can see at shorter period
there is no specific trend,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5363-1
00:26:46.946 --> 00:26:50.046
<v Rashid Shams>although there is a lot of
spread and as we move to longer</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5363-2
00:26:50.046 --> 00:26:53.304
<v Rashid Shams>periods, there is some trend at
higher scivias 3 values which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5363-3
00:26:53.304 --> 00:26:56.247
<v Rashid Shams>was again expected because
higher values represent some</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5363-4
00:26:56.247 --> 00:26:59.032
<v Rashid Shams>kind of heterogeneity
availability at a site because</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5363-5
00:26:59.032 --> 00:27:02.079
<v Rashid Shams>we are also accounting for
horizontal and variability and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5363-6
00:27:02.079 --> 00:27:03.183
<v Rashid Shams>vertical variability.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5379-0
00:27:04.203 --> 00:27:07.606
<v Rashid Shams>So this parameter also shows
some promise to work as</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5379-1
00:27:07.606 --> 00:27:08.313
<v Rashid Shams>accounting.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5404-0
00:27:08.323 --> 00:27:12.440
<v Rashid Shams>Some unaccounted side effects in
commotion models, especially for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5404-1
00:27:12.440 --> 00:27:16.120
<v Rashid Shams>Socal because we looked at these
trends for all the basins</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5404-2
00:27:16.120 --> 00:27:17.243
<v Rashid Shams>combined in Socal.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5436-0
00:27:19.333 --> 00:27:23.189
<v Rashid Shams>Moving on to another parameter
that was interesting stand</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5436-1
00:27:23.189 --> 00:27:26.913
<v Rashid Shams>deviation of absolute difference
between Z 1.5 and ZCP.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5464-0
00:27:27.423 --> 00:27:31.331
<v Rashid Shams>So Z 1.5 is the cemetery based
in depth and then we have ZCB</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5464-1
00:27:31.331 --> 00:27:33.573
<v Rashid Shams>which is Christian basement
depth.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5499-0
00:27:34.523 --> 00:27:38.253
<v Rashid Shams>So be when we looked at site
test deals with the parameter,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5499-1
00:27:38.253 --> 00:27:41.983
<v Rashid Shams>we again saw there was some
trend and spread as we moved to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5499-2
00:27:41.983 --> 00:27:44.843
<v Rashid Shams>longer periods, especially at
longer periods.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5524-0
00:27:44.853 --> 00:27:48.382
<v Rashid Shams>There is a downgoing trend that
we see when we look at the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5524-1
00:27:48.382 --> 00:27:51.193
<v Rashid Shams>yellow color plus markers which
are bin means.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5544-0
00:27:51.543 --> 00:27:56.476
<v Rashid Shams>This again showed that this
parameter would have, uh, uh,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5544-1
00:27:56.476 --> 00:28:00.643
<v Rashid Shams>decent and good pretty power
that could be used.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5567-0
00:28:02.553 --> 00:28:06.337
<v Rashid Shams>To harness some sighted effects,
there is not accounted in ground</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5567-1
00:28:06.337 --> 00:28:07.083
<v Rashid Shams>motion model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5647-0
00:28:08.343 --> 00:28:11.500
<v Rashid Shams>There was some parameters that
were interesting, although we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5647-1
00:28:11.500 --> 00:28:14.813
<v Rashid Shams>looked at a lot of parameters,
some more parameters are such as</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5647-2
00:28:14.813 --> 00:28:17.918
<v Rashid Shams>slope of the basins, deepest
point of Basin, Pedro context,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5647-3
00:28:17.918 --> 00:28:21.024
<v Rashid Shams>which was the distance from the
deepest point in the basin,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5647-4
00:28:21.024 --> 00:28:23.819
<v Rashid Shams>bedrock contact to the
particular site, distance from</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5647-5
00:28:23.819 --> 00:28:26.873
<v Rashid Shams>basin centroid which was the
distance from the centroid of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5647-6
00:28:26.873 --> 00:28:29.513
<v Rashid Shams>the basin in the sense it was
based in centricity.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5691-0
00:28:30.043 --> 00:28:33.870
<v Rashid Shams>This is from the process level
channel or any old river channel</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5691-1
00:28:33.870 --> 00:28:36.920
<v Rashid Shams>and aspect of the listen
basement depth, but these</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5691-2
00:28:36.920 --> 00:28:40.567
<v Rashid Shams>parameters didn't exhibit any
appreciable bias on trends, at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5691-3
00:28:40.567 --> 00:28:41.943
<v Rashid Shams>least in loss as basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5708-0
00:28:42.453 --> 00:28:45.507
<v Rashid Shams>This disregards any pretty power
of these parameters to capture</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5708-1
00:28:45.507 --> 00:28:47.273
<v Rashid Shams>additional unaccounted side
effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5738-0
00:28:47.283 --> 00:28:50.256
<v Rashid Shams>Although they could show
potential for different basins</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5738-1
00:28:50.256 --> 00:28:53.708
<v Rashid Shams>or different sedimentary basins
around the world, which is still</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5738-2
00:28:53.708 --> 00:28:54.823
<v Rashid Shams>need to be looked at.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5773-0
00:28:56.023 --> 00:28:59.524
<v Rashid Shams>So some key takeaways from this
part of the presentation is that</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5773-1
00:28:59.524 --> 00:29:02.647
<v Rashid Shams>this theory is doing a good job
in capturing average side</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5773-2
00:29:02.647 --> 00:29:05.664
<v Rashid Shams>effects, but geometric
parameters exhibit applicational</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5773-3
00:29:05.664 --> 00:29:05.933
<v Rashid Shams>bias.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5788-0
00:29:06.183 --> 00:29:09.042
<v Rashid Shams>Some of the parameters exhibit
additional bias and spread in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5788-1
00:29:09.042 --> 00:29:09.933
<v Rashid Shams>the site residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-0
00:29:10.163 --> 00:29:13.751
<v Rashid Shams>In Los Angeles Basin, so there
are interesting to look at and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-1
00:29:13.751 --> 00:29:17.397
<v Rashid Shams>distance to basin margin helps
us to set a threshold for basin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-2
00:29:17.397 --> 00:29:21.101
<v Rashid Shams>margin sites which is helps us
to differentiate based in margin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-3
00:29:21.101 --> 00:29:24.863
<v Rashid Shams>of Basin edge sites from actual
basin sites in Los Angeles Basin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-4
00:29:24.863 --> 00:29:28.335
<v Rashid Shams>3 parameters that were very
interesting is SI average SIDS,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-5
00:29:28.335 --> 00:29:32.097
<v Rashid Shams>30 for Socal stand deviation of
JCB and Sen Division of Absolute</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-6
00:29:32.097 --> 00:29:35.917
<v Rashid Shams>difference between C and 1.5 for
loss and it's basin because they</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-7
00:29:35.917 --> 00:29:39.620
<v Rashid Shams>showed some significant trends
and bias essai average parameter</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5906-8
00:29:39.620 --> 00:29:43.093
<v Rashid Shams>also acts as a classifier for
basic and basic margin sites.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5929-0
00:29:43.173 --> 00:29:46.733
<v Rashid Shams>And could be could act like
could work in conjugation with</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5929-1
00:29:46.733 --> 00:29:50.173
<v Rashid Shams>distance from basin margin to
identify Basin Edge sites.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5932-0
00:29:52.683 --> 00:29:53.243
<v Rashid Shams>Moving on.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/5943-0
00:29:55.583 --> 00:29:56.953
<v Rashid Shams>To the third part of the
presentation.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6010-0
00:29:58.233 --> 00:30:01.745
<v Rashid Shams>So as we looked at different
geometric parameters, this part</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6010-1
00:30:01.745 --> 00:30:05.373
<v Rashid Shams>of the presentation will in uh
revolve around modeling some of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6010-2
00:30:05.373 --> 00:30:08.482
<v Rashid Shams>the interesting parameters that
we looked at and then</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6010-3
00:30:08.482 --> 00:30:11.936
<v Rashid Shams>incorporating those parameter
information model and finally</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6010-4
00:30:11.936 --> 00:30:15.621
<v Rashid Shams>performing evaluation of those
modified commotion model against</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6010-5
00:30:15.621 --> 00:30:18.903
<v Rashid Shams>the original motion model and
see if we can capture some</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6010-6
00:30:18.903 --> 00:30:20.343
<v Rashid Shams>unaccounted side effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6024-0
00:30:20.403 --> 00:30:23.761
<v Rashid Shams>And if these parameters can help
us uncovering some unaccounted</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6024-1
00:30:23.761 --> 00:30:24.443
<v Rashid Shams>side effects?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6038-0
00:30:26.613 --> 00:30:29.929
<v Rashid Shams>So modeling of the parameters,
we selected three major</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6038-1
00:30:29.929 --> 00:30:30.593
<v Rashid Shams>parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6055-0
00:30:30.653 --> 00:30:34.048
<v Rashid Shams>Again, Sivas, 30s, ten deviation
of absolute difference and stand</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6055-1
00:30:34.048 --> 00:30:34.923
<v Rashid Shams>deviation of CCB.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6067-0
00:30:35.133 --> 00:30:37.983
<v Rashid Shams>So plot on the right shows
scivias theory.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6074-0
00:30:38.513 --> 00:30:39.943
<v Rashid Shams>The Black Line is the best fit.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6102-0
00:30:39.993 --> 00:30:43.757
<v Rashid Shams>We use a second degree two
degree polynomial, best fit</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6102-1
00:30:43.757 --> 00:30:48.000
<v Rashid Shams>functional form to model the
parameters so we can see the bin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6102-2
00:30:48.000 --> 00:30:48.753
<v Rashid Shams>means they.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6115-0
00:30:50.403 --> 00:30:53.853
<v Rashid Shams>Uh, they align decently with the
best fit lines.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6123-0
00:30:53.863 --> 00:30:55.653
<v Rashid Shams>We don't have any overfitting,
underfitting.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6157-0
00:30:56.443 --> 00:31:00.997
<v Rashid Shams>Similarly, this plot is for 10
division of CB where again the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6157-1
00:31:00.997 --> 00:31:05.478
<v Rashid Shams>best fit is shown in the Black
line and this is for that her</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6157-2
00:31:05.478 --> 00:31:06.213
<v Rashid Shams>parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6168-0
00:31:07.043 --> 00:31:10.093
<v Rashid Shams>So we use this functional form
moving on.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6211-0
00:31:10.103 --> 00:31:12.931
<v Rashid Shams>Now I will discuss how did we
incorporate the geometric</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6211-1
00:31:12.931 --> 00:31:16.162
<v Rashid Shams>parameter models for all these
three individual parameters, and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6211-2
00:31:16.162 --> 00:31:19.243
<v Rashid Shams>then we conducted carried out
the residual analysis again to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6211-3
00:31:19.243 --> 00:31:22.323
<v Rashid Shams>get a new set of residuals which
we will use for comparison.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6237-0
00:31:23.503 --> 00:31:27.037
<v Rashid Shams>So we have three major
components in the ground motion</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6237-1
00:31:27.037 --> 00:31:29.993
<v Rashid Shams>model estimate we have in a
commercial model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6260-0
00:31:30.003 --> 00:31:32.574
<v Rashid Shams>We have even component path
component and the site component</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6260-1
00:31:32.574 --> 00:31:35.273
<v Rashid Shams>site component is the component
where we are majorly interested</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6260-2
00:31:35.273 --> 00:31:35.863
<v Rashid Shams>in this study.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6283-0
00:31:37.493 --> 00:31:40.881
<v Rashid Shams>So we have the site component
for the ground motion model that</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6283-1
00:31:40.881 --> 00:31:42.763
<v Rashid Shams>we are looking at, which is
bored.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6304-0
00:31:42.773 --> 00:31:45.344
<v Rashid Shams>All 2014 has three major
component initially linear</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6304-1
00:31:45.344 --> 00:31:48.113
<v Rashid Shams>component, nonlinear component
and the basin component.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6329-0
00:31:48.123 --> 00:31:51.912
<v Rashid Shams>We add the geometric model
component in the site component</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6329-1
00:31:51.912 --> 00:31:55.123
<v Rashid Shams>of the commotion model, so we
term it as sub Geo.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6340-0
00:31:55.313 --> 00:31:58.060
<v Rashid Shams>So in this geometric parameter
component, we have three</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6340-1
00:31:58.060 --> 00:31:58.943
<v Rashid Shams>individual models.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6361-0
00:31:59.273 --> 00:32:02.963
<v Rashid Shams>We have three individual models
based on all three parameters</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6361-1
00:32:02.963 --> 00:32:05.403
<v Rashid Shams>that we looked at in the
previous slide.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6395-0
00:32:05.693 --> 00:32:08.957
<v Rashid Shams>So we'll model these, see
parameter individually and then</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6395-1
00:32:08.957 --> 00:32:12.052
<v Rashid Shams>we'll incorporate and look at
each of these parameters</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6395-2
00:32:12.052 --> 00:32:15.373
<v Rashid Shams>incorporate as a FG O in the
promotion model individually.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6443-0
00:32:17.313 --> 00:32:21.341
<v Rashid Shams>Uh, so moving on then, once we
have the modified commotion</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6443-1
00:32:21.341 --> 00:32:25.300
<v Rashid Shams>model with this geometric
parameter model incorporated in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6443-2
00:32:25.300 --> 00:32:29.191
<v Rashid Shams>the site component, we will
compute the new set of total</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6443-3
00:32:29.191 --> 00:32:33.151
<v Rashid Shams>residuals, which will be again
data minus modified ground</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6443-4
00:32:33.151 --> 00:32:34.653
<v Rashid Shams>motion model estimate.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6451-0
00:32:35.943 --> 00:32:37.503
<v Rashid Shams>Then we'll partition these.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6456-0
00:32:38.383 --> 00:32:39.503
<v Rashid Shams>Uh, totally.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6497-0
00:32:39.513 --> 00:32:42.200

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6497-1
00:32:42.200 --> 00:32:45.161
<v Rashid Shams>residuals where within evenness
duals we again partitioning into</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6497-2
00:32:45.161 --> 00:32:47.393
<v Rashid Shams>a new set of site test to and
remaining as well.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6524-0
00:32:47.403 --> 00:32:50.346
<v Rashid Shams>So based on these three
parameters and T individual</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6524-1
00:32:50.346 --> 00:32:53.232
<v Rashid Shams>convolutional model
incorporated, we'll have three</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6524-2
00:32:53.232 --> 00:32:55.213
<v Rashid Shams>individual sets of site
residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6581-0
00:32:55.283 --> 00:32:59.259
<v Rashid Shams>After carrying out this residual
analysis, so one set of the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6581-1
00:32:59.259 --> 00:33:03.365
<v Rashid Shams>first, the site residuals will
be based on SI metric parameter</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6581-2
00:33:03.365 --> 00:33:07.275
<v Rashid Shams>model, second value based on
sand division of ZCB parameter</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6581-3
00:33:07.275 --> 00:33:11.186
<v Rashid Shams>model and the third set will be
based on stand deviation of</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6581-4
00:33:11.186 --> 00:33:13.663
<v Rashid Shams>absolute difference parameter
models.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6596-0
00:33:14.213 --> 00:33:17.453
<v Rashid Shams>Finally, we'll be calculating
variability of these.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6617-0
00:33:20.263 --> 00:33:23.541
<v Rashid Shams>And usually obtained residuals
site residuals based on the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6617-1
00:33:23.541 --> 00:33:25.153
<v Rashid Shams>modified ground motion model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6688-0
00:33:25.403 --> 00:33:28.995
<v Rashid Shams>We'll be specifically looking at
free S2S, which is the standard</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6688-1
00:33:28.995 --> 00:33:31.979
<v Rashid Shams>deviation of site residuals
representing site to site</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6688-2
00:33:31.979 --> 00:33:35.074
<v Rashid Shams>variability, and it could be it
helps us to interpret a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6688-3
00:33:35.074 --> 00:33:38.500
<v Rashid Shams>dispersion of the site residuals
for given intensity measure,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6688-4
00:33:38.500 --> 00:33:41.816
<v Rashid Shams>which is finally we used to
evaluate the performance of our</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6688-5
00:33:41.816 --> 00:33:45.021
<v Rashid Shams>ground motion of our modified
ground motion model against</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6688-6
00:33:45.021 --> 00:33:46.403
<v Rashid Shams>original condition model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6715-0
00:33:47.703 --> 00:33:51.006
<v Rashid Shams>So we first start with looking
some looking at some visual</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6715-1
00:33:51.006 --> 00:33:54.253
<v Rashid Shams>visuals for site test tools that
we were doing initially.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6736-0
00:33:54.343 --> 00:33:57.638
<v Rashid Shams>So we first start with the IS3
parameter which is modeled for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6736-1
00:33:57.638 --> 00:33:58.223
<v Rashid Shams>full Socal.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6750-0
00:33:59.233 --> 00:34:02.342
<v Rashid Shams>So on the left I have side
residuals from the original</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6750-1
00:34:02.342 --> 00:34:03.473
<v Rashid Shams>ground motion model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6763-0
00:34:05.043 --> 00:34:07.953
<v Rashid Shams>Uh BS14 complement with the
basin, uh.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6811-0
00:34:07.963 --> 00:34:11.650
<v Rashid Shams>Socal Basin model so I assigned
as duals for four periods on the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6811-1
00:34:11.650 --> 00:34:15.337
<v Rashid Shams>right, I have the site residuals
from the modified ground motion</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6811-2
00:34:15.337 --> 00:34:18.797
<v Rashid Shams>model after incorporating the
scivias theory based geometric</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6811-3
00:34:18.797 --> 00:34:21.803
<v Rashid Shams>parameter model in the original
ground motion model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6856-0
00:34:22.613 --> 00:34:26.920
<v Rashid Shams>So if we specifically look at
shorter periods, we see there is</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6856-1
00:34:26.920 --> 00:34:31.227
<v Rashid Shams>some addition spread, but if we
look at longer periods on plot</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6856-2
00:34:31.227 --> 00:34:35.329
<v Rashid Shams>on the left, it has some friend
that we are eliminating and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6856-3
00:34:35.329 --> 00:34:36.013
<v Rashid Shams>capturing.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6903-0
00:34:36.123 --> 00:34:39.325
<v Rashid Shams>If we look at the plot on right
for longer periods at once,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6903-1
00:34:39.325 --> 00:34:42.581
<v Rashid Shams>again 3 second, this tells us
that the parameter is reducing</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6903-2
00:34:42.581 --> 00:34:45.997
<v Rashid Shams>spread and spread trend and bias
in residuals, which means that</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6903-3
00:34:45.997 --> 00:34:49.092
<v Rashid Shams>we are incorporating some side
effects that was not being</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6903-4
00:34:49.092 --> 00:34:49.573
<v Rashid Shams>captured.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6912-0
00:34:49.893 --> 00:34:51.663
<v Rashid Shams>At least we can see it visually
here.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6920-0
00:34:52.423 --> 00:34:56.773
<v Rashid Shams>We move on to look at the mean
site residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6952-0
00:34:58.493 --> 00:35:01.247
<v Rashid Shams>So the plot top two plots show
the mean size residuals for</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6952-1
00:35:01.247 --> 00:35:03.909
<v Rashid Shams>different site categories or
different lines are covered</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6952-2
00:35:03.909 --> 00:35:05.683
<v Rashid Shams>colored by different site
categories.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6985-0
00:35:06.013 --> 00:35:09.752
<v Rashid Shams>The plot A is from the original
ground motion model BSA 14 Socal</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6985-1
00:35:09.752 --> 00:35:13.203
<v Rashid Shams>and the plot B is after we
complement that conversion model</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/6985-2
00:35:13.203 --> 00:35:13.433
<v Rashid Shams>bit.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7017-0
00:35:13.443 --> 00:35:16.678
<v Rashid Shams>The geometric parameter model,
so we can clearly see there is</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7017-1
00:35:16.678 --> 00:35:19.912
<v Rashid Shams>some reduction in the mean side
item, which means that we are</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7017-2
00:35:19.912 --> 00:35:21.843
<v Rashid Shams>capturing more average side
effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7030-0
00:35:21.933 --> 00:35:26.633
<v Rashid Shams>The the lines are moving closer
to 00 line.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7062-0
00:35:27.403 --> 00:35:32.099
<v Rashid Shams>The plots below these two plots
plot CDE&amp;F shows comparison</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7062-1
00:35:32.099 --> 00:35:36.721
<v Rashid Shams>between means items for original
permission model and modified</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7062-2
00:35:36.721 --> 00:35:40.243
<v Rashid Shams>permission model for different
site categories.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7105-0
00:35:40.253 --> 00:35:43.643
<v Rashid Shams>So first the proxy shows for
Base insights where we see the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7105-1
00:35:43.643 --> 00:35:47.372
<v Rashid Shams>dashed line is from the original
ground motion model and the soil</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7105-2
00:35:47.372 --> 00:35:50.763
<v Rashid Shams>line is after we incorporate the
geometric parameter model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7122-0
00:35:51.013 --> 00:35:54.127
<v Rashid Shams>So we see the at least for
longer periods, we are moving</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7122-1
00:35:54.127 --> 00:35:54.783
<v Rashid Shams>closer to 0.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7135-0
00:35:54.893 --> 00:35:58.483
<v Rashid Shams>So there is a reduction in uh
site.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7145-0
00:35:58.993 --> 00:36:02.523
<v Rashid Shams>The there is a reduction in mean
site as duals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7151-0
00:36:02.993 --> 00:36:03.583
<v Rashid Shams>Similarly for.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7164-0
00:36:05.273 --> 00:36:09.203
<v Rashid Shams>Similarly, we have similar
trends for Basin and Basin Edge</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7164-1
00:36:09.203 --> 00:36:09.603

00:36:09.773 --> 00:36:12.483
<v Rashid Shams>So this is also working for
Basin Edge sites.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7206-0
00:36:13.013 --> 00:36:17.295
<v Rashid Shams>Similarly, in plot ENFP for
Valley sites and mountain sites,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7206-1
00:36:17.295 --> 00:36:21.577
<v Rashid Shams>we are still eliminating and
reducing the mean side terms by</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7206-2
00:36:21.577 --> 00:36:23.473
<v Rashid Shams>moving it through the zero.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7278-0
00:36:25.763 --> 00:36:29.197
<v Rashid Shams>Now moving on, looking at the
fee S2S, which is the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7278-1
00:36:29.197 --> 00:36:33.160
<v Rashid Shams>variability or site to site

00:36:41.351 --> 00:36:45.512
<v Rashid Shams>the modified promotion model and
the soil line is the original</v>

00:36:47.303 --> 00:36:51.388
<v Rashid Shams>The bottom plot shows percent

00:36:51.388 --> 00:36:55.279
<v Rashid Shams>at the magenta line, which is

00:37:28.703 --> 00:37:32.177
<v Rashid Shams>Although we had reduction in

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7450-1
00:37:32.177 --> 00:37:35.823
<v Rashid Shams>were reducing or capturing more
average side effects in basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7463-0
00:37:35.833 --> 00:37:37.483
<v Rashid Shams>But we don't have any reduction

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7480-0
00:37:37.493 --> 00:37:41.369
<v Rashid Shams>2S for the reason behind this,
no reduction in PS2 is for base</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7480-1
00:37:41.369 --> 00:37:41.923
<v Rashid Shams>insights.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7550-0
00:37:41.933 --> 00:37:45.379
<v Rashid Shams>Specifically, could be because
we are capturing major major</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7550-1
00:37:45.379 --> 00:37:48.539
<v Rashid Shams>part of this basin related
variability because we have</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7550-2
00:37:48.539 --> 00:37:52.100
<v Rashid Shams>already accounted for this that
variability while when we are</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7550-3
00:37:52.100 --> 00:37:55.719
<v Rashid Shams>because we are using so-called
basin model from New Year older</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7550-4
00:37:55.719 --> 00:37:59.108
<v Rashid Shams>in 22 and we are also using
basin depths and B study which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7550-5
00:37:59.108 --> 00:38:02.153
<v Rashid Shams>is also complemented
complemented by baseline model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7593-0
00:38:02.483 --> 00:38:05.828
<v Rashid Shams>So this could be one reason why
we are not seeing any direction</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7593-1
00:38:05.828 --> 00:38:08.859
<v Rashid Shams>if he S2S for base insights,
although we see reduction in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7593-2
00:38:08.859 --> 00:38:11.943
<v Rashid Shams>fees 2S for non basins such as
valleys and mountain hills.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7623-0
00:38:14.023 --> 00:38:16.986
<v Rashid Shams>Now moving on to the second
geometric parameter model, which</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7623-1
00:38:16.986 --> 00:38:19.950
<v Rashid Shams>was stand deviation of absolute
difference between Christian</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7623-2
00:38:19.950 --> 00:38:22.233
<v Rashid Shams>basement depth and sedimentary
basement depth.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7654-0
00:38:22.403 --> 00:38:25.434
<v Rashid Shams>So we again have uh site
residuals from the original</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7654-1
00:38:25.434 --> 00:38:29.038
<v Rashid Shams>machine model on the left and
site residuals from the modified</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7654-2
00:38:29.038 --> 00:38:30.983
<v Rashid Shams>ground motion model on the
right.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7663-0
00:38:31.793 --> 00:38:33.743
<v Rashid Shams>And we have four pair ranges.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7690-0
00:38:33.753 --> 00:38:37.799
<v Rashid Shams>We can clearly see the if we
follow the red curly braces here</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7690-1
00:38:37.799 --> 00:38:41.323
<v Rashid Shams>we can see there is a
significant reduction in spread</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7690-2
00:38:41.323 --> 00:38:42.563
<v Rashid Shams>as shorter periods.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7733-0
00:38:43.793 --> 00:38:47.388
<v Rashid Shams>Uh, and if you compare the plot
on the left and the right, there</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7733-1
00:38:47.388 --> 00:38:50.984
<v Rashid Shams>is a reduction in spread and if
you move to longer periods there</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7733-2
00:38:50.984 --> 00:38:54.303
<v Rashid Shams>is some trend on the prod on the
uh left at longer periods.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7751-0
00:38:54.313 --> 00:38:59.337
<v Rashid Shams>But we remove or eliminate this
trend as after incorporating the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7751-1
00:38:59.337 --> 00:39:00.883
<v Rashid Shams>geometric parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7780-0
00:39:01.253 --> 00:39:05.409
<v Rashid Shams>So by this visual inspection we
can say that the stand division</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7780-1
00:39:05.409 --> 00:39:09.694
<v Rashid Shams>of absolute difference parameter
is helping us reduce some spread</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7780-2
00:39:09.694 --> 00:39:11.383
<v Rashid Shams>and bias inside residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7784-0
00:39:11.613 --> 00:39:14.103
<v Rashid Shams>Insight response in Los Angeles
basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7814-0
00:39:15.813 --> 00:39:19.986
<v Rashid Shams>Moving on to the third and the
final geometric parameter model,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7814-1
00:39:19.986 --> 00:39:23.964
<v Rashid Shams>again we visually see on the
plot on the left shows original</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7814-2
00:39:23.964 --> 00:39:25.333
<v Rashid Shams>commotion model side.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7846-0
00:39:25.343 --> 00:39:28.606
<v Rashid Shams>This duals and plot on the right
shows modified ground motion,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7846-1
00:39:28.606 --> 00:39:31.870
<v Rashid Shams>model sites, duals, and if we
again look at longer periods, we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7846-2
00:39:31.870 --> 00:39:33.113
<v Rashid Shams>can see there was trend.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7862-0
00:39:34.043 --> 00:39:37.187
<v Rashid Shams>Uh for from the original site as
well, and we eliminate these</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7862-1
00:39:37.187 --> 00:39:37.593
<v Rashid Shams>friends.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7883-0
00:39:39.143 --> 00:39:41.940
<v Rashid Shams>Uh, as we'll cooperative
incorporate these geometric</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7883-1
00:39:41.940 --> 00:39:44.473
<v Rashid Shams>parameter model based on stand
division of CFB.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7896-0
00:39:45.303 --> 00:39:48.153
<v Rashid Shams>So we again reducing and
capturing some unaccounted side</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7896-1
00:39:48.153 --> 00:39:48.553
<v Rashid Shams>effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7917-0
00:39:49.023 --> 00:39:52.295
<v Rashid Shams>So now comparing the performance
of all these models, so first</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7917-1
00:39:52.295 --> 00:39:53.853
<v Rashid Shams>we'll look at mean side terms.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7930-0
00:39:55.103 --> 00:39:57.373
<v Rashid Shams>Though the miss is the mean
means of sight residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7956-0
00:39:57.643 --> 00:40:00.535
<v Rashid Shams>So which will help us to see how
much average effect more average</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/7956-1
00:40:00.535 --> 00:40:02.813
<v Rashid Shams>effect, average side effects
that we are capturing.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8027-0
00:40:03.633 --> 00:40:07.620
<v Rashid Shams>So the black dashed line is for
the Socal original condition</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8027-1
00:40:07.620 --> 00:40:11.737
<v Rashid Shams>model and the red dashed line is
geometric ground motion model</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8027-2
00:40:11.737 --> 00:40:15.136
<v Rashid Shams>modified with scivias 30
parameter blue is for gram</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8027-3
00:40:15.136 --> 00:40:19.319
<v Rashid Shams>motion model modifier with stand
deviation of ZCB parameter and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8027-4
00:40:19.319 --> 00:40:22.782
<v Rashid Shams>the green one is the motion
model modified with Stan</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8027-5
00:40:22.782 --> 00:40:25.593
<v Rashid Shams>division of absolute difference
parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8032-0
00:40:25.753 --> 00:40:26.393
<v Rashid Shams>So we can see.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8057-0
00:40:28.523 --> 00:40:32.568
<v Rashid Shams>Uh, especially at longer periods
there is some reduction in when</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8057-1
00:40:32.568 --> 00:40:34.933
<v Rashid Shams>we incorporate the SSIS 30
parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8113-0
00:40:36.333 --> 00:40:39.407
<v Rashid Shams>There is more direction for the
blue one, which is stand</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8113-1
00:40:39.407 --> 00:40:42.696
<v Rashid Shams>division of ECB and we see the
most significant reduction in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8113-2
00:40:42.696 --> 00:40:46.040
<v Rashid Shams>mean side terms, which is going
almost flat at longer periods</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8113-3
00:40:46.040 --> 00:40:49.384
<v Rashid Shams>when we incorporate the stand
division of absolute difference</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8113-4
00:40:49.384 --> 00:40:51.433
<v Rashid Shams>parameter in the ground motion
model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8126-0
00:40:52.733 --> 00:40:55.933
<v Rashid Shams>Next we look again compare site
to site dispersion variability.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8144-0
00:40:57.243 --> 00:41:00.056
<v Rashid Shams>Uh across RPM ranges for all the
for all the three hermetic</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8144-1
00:41:00.056 --> 00:41:00.853
<v Rashid Shams>parameter models.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8159-0
00:41:01.543 --> 00:41:06.253
<v Rashid Shams>Again, the black dashed line is
for uh original formation model.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8233-0
00:41:06.473 --> 00:41:09.836
<v Rashid Shams>We see that the red line
coincides with the Black line</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8233-1
00:41:09.836 --> 00:41:13.688
<v Rashid Shams>because the SSIS 30 parameter is
modeled for Socal in general,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8233-2
00:41:13.688 --> 00:41:17.479
<v Rashid Shams>not for lossless basin, but we
see reduction in FS2S for from</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8233-3
00:41:17.479 --> 00:41:21.087
<v Rashid Shams>other two parameters, which is
the blue line from standard</v>

00:41:21.087 --> 00:41:24.694
<v Rashid Shams>division of GCB and we have the
most significant reduction</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8233-5
00:41:24.694 --> 00:41:26.223

00:41:26.653 --> 00:41:30.853
<v Rashid Shams>For using this stand divisional
absolute difference parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8244-0
00:41:33.193 --> 00:41:33.553
<v Rashid Shams>So.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8271-0
00:41:36.233 --> 00:41:39.895
<v Rashid Shams>All three models showed
significant reduction and they</v>

00:42:04.013 --> 00:42:04.783
<v Rashid Shams>is non basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8350-0
00:42:04.793 --> 00:42:07.903
<v Rashid Shams>But it didn't show any
improvement for basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8378-0
00:42:08.613 --> 00:42:12.868
<v Rashid Shams>So in conclusion, these three
geometric parameters perform</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8378-1
00:42:12.868 --> 00:42:16.763
<v Rashid Shams>well and they show some
significant some reduction in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8378-2
00:42:16.763 --> 00:42:20.153
<v Rashid Shams>PS2, S and capturing unaccounted
side effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8436-0
00:42:22.543 --> 00:42:27.038
<v Rashid Shams>So to summarize everything in
this presentation, I presented a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8436-1
00:42:27.038 --> 00:42:31.177
<v Rashid Shams>framework which focused on
defining basin depth, which is</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8436-2
00:42:31.177 --> 00:42:35.244
<v Rashid Shams>we looked at CMH based CB
crystal based on depth and GSB</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8436-3
00:42:35.244 --> 00:42:39.454
<v Rashid Shams>sedimentary basement depth which
help us to calculate some</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8436-4
00:42:39.454 --> 00:42:40.953
<v Rashid Shams>geometric parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8443-0
00:42:41.293 --> 00:42:43.063
<v Rashid Shams>We identified different
geometric parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8472-0
00:42:43.073 --> 00:42:46.887
<v Rashid Shams>We looked at and explored a
suitor parameters, and then we</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8472-1
00:42:46.887 --> 00:42:50.636
<v Rashid Shams>narrowed down to three major
parameters, which we further</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8472-2
00:42:50.636 --> 00:42:51.153
<v Rashid Shams>modeled.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8487-0
00:42:51.463 --> 00:42:53.736
<v Rashid Shams>We modeled the best performing
parameters from the pseudo</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8487-1
00:42:53.736 --> 00:42:54.873
<v Rashid Shams>parameters that we looked at.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8539-0
00:42:55.163 --> 00:42:58.717
<v Rashid Shams>We incorporate those geometric
parameter models in the motion</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8539-1
00:42:58.717 --> 00:43:01.871
<v Rashid Shams>model and evaluated the
performance of these models if</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8539-2
00:43:01.871 --> 00:43:05.425
<v Rashid Shams>the to see if we are ohk ohk
capturing someone unaccounted or</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8539-3
00:43:05.425 --> 00:43:08.579
<v Rashid Shams>two dimensional 3 dimensional
side effects using these</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8539-4
00:43:08.579 --> 00:43:09.783
<v Rashid Shams>geometric parameters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8597-0
00:43:10.263 --> 00:43:13.718
<v Rashid Shams>The model developed and the
parameter discussed are strictly</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8597-1
00:43:13.718 --> 00:43:17.400
<v Rashid Shams>only limited to losses basis and
Socal because their performance</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8597-2
00:43:17.400 --> 00:43:20.628
<v Rashid Shams>could change depending on
different types of sedimentary</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8597-3
00:43:20.628 --> 00:43:24.367
<v Rashid Shams>basis, we only looked at for the
Los Angeles Basin in general due</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8597-4
00:43:24.367 --> 00:43:26.123
<v Rashid Shams>to data issues in other basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8615-0
00:43:27.343 --> 00:43:30.601
<v Rashid Shams>This framework would be adopted
for other bases and similar</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8615-1
00:43:30.601 --> 00:43:32.773
<v Rashid Shams>geometric parameters could be
explored.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8634-0
00:43:32.823 --> 00:43:35.193
<v Rashid Shams>This could be adopted for the
other sedimentary basis.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8695-0
00:43:35.343 --> 00:43:38.593
<v Rashid Shams>These geometric parameters are
much simpler to compute for the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8695-1
00:43:38.593 --> 00:43:41.585
<v Rashid Shams>regions where we don't have
enough site specific data, so</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8695-2
00:43:41.585 --> 00:43:44.836
<v Rashid Shams>this could be helpful at least
some parameters which are based</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8695-3
00:43:44.836 --> 00:43:47.983
<v Rashid Shams>on simple geometric metrics such
as distance based in margin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8695-4
00:43:47.983 --> 00:43:51.130
<v Rashid Shams>could be helpful to look at
based on edge sites and based on</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8695-5
00:43:51.130 --> 00:43:51.543
<v Rashid Shams>effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8752-0
00:43:52.793 --> 00:43:55.835
<v Rashid Shams>Uh, parameters that this also
based margin SI average also</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8752-1
00:43:55.835 --> 00:43:58.826
<v Rashid Shams>contribute towards better
understanding of basic effects,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8752-2
00:43:58.826 --> 00:44:01.972
<v Rashid Shams>at least if they are helping us
to look at difference inside</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8752-3
00:44:01.972 --> 00:44:05.272
<v Rashid Shams>response in basin edge size and
based in edge and could help us</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8752-4
00:44:05.272 --> 00:44:07.593
<v Rashid Shams>classify based on edge and
basing the sites.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8797-0
00:44:08.283 --> 00:44:12.575
<v Rashid Shams>Yes, I will study work well for
non basins specifically values</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8797-1
00:44:12.575 --> 00:44:16.730
<v Rashid Shams>and mountain hills and standard
deviation of CB and standing</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8797-2
00:44:16.730 --> 00:44:20.545
<v Rashid Shams>mission website difference in
the CB and 1.5 short some</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8797-3
00:44:20.545 --> 00:44:21.363
<v Rashid Shams>performance.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8809-0
00:44:21.653 --> 00:44:25.700
<v Rashid Shams>The good performance for
sedimentary based in size and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8809-1
00:44:25.700 --> 00:44:26.583
<v Rashid Shams>Los Angeles.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8872-0
00:44:28.983 --> 00:44:32.445
<v Rashid Shams>Uh, some of the next step that
we yeah, think of aim to look at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8872-1
00:44:32.445 --> 00:44:35.583
<v Rashid Shams>is validating and exploring
these geometric parameters in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8872-2
00:44:35.583 --> 00:44:39.045
<v Rashid Shams>other symmetry basins is local
or other basins around the world</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8872-3
00:44:39.045 --> 00:44:42.183
<v Rashid Shams>to see if they work well for
those boosts basins as well.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8915-0
00:44:42.943 --> 00:44:47.010
<v Rashid Shams>Some of the basins that where we
could look at these parameters</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8915-1
00:44:47.010 --> 00:44:51.076
<v Rashid Shams>could be based in Beijing, Tokyo
Inlet based in Alaska, Seattle</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8915-2
00:44:51.076 --> 00:44:54.063
<v Rashid Shams>and Tacoma Basin, Puget Lowland

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8949-0
00:45:12.013 --> 00:45:14.303
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Yes, thanks for a great talk.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8974-0
00:45:14.713 --> 00:45:18.150
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>I was wondering if you you found
including the Asmus in your</v>

00:45:18.150 --> 00:45:19.503
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>edger based integration.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8985-0
00:45:19.563 --> 00:45:22.223
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>I was thinking about the 1995
away earthquake.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/8988-0
00:45:22.453 --> 00:45:22.763
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>There was.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9002-0
00:45:22.773 --> 00:45:25.651
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>The damage was along the edge of
the basin and there was this</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9002-1
00:45:25.651 --> 00:45:26.023
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>exactly.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9052-0
00:45:26.033 --> 00:45:30.135
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>There was kind of as we go back
in the edge of the basin with</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9052-1
00:45:30.135 --> 00:45:34.236
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>the fault in the basin working
done that either baby asmas in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9052-2
00:45:34.236 --> 00:45:38.404
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>the education thing and then if
think about what you have Kobe</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9052-3
00:45:38.404 --> 00:45:39.463
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>testing effects.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9057-0
00:45:40.583 --> 00:45:42.153
<v Rashid Shams>Yeah, that is a good point.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9062-0
00:45:42.163 --> 00:45:43.573
<v Rashid Shams>We are we.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9103-0
00:45:43.583 --> 00:45:46.750
<v Rashid Shams>We didn't look at any specific
azimuth related parameter when</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9103-1
00:45:46.750 --> 00:45:49.559
<v Rashid Shams>we're looking at metric
parameters, but we are looking</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9103-2
00:45:49.559 --> 00:45:52.676
<v Rashid Shams>at azimuth based effects right
now because we are looking at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9103-3
00:45:52.676 --> 00:45:53.493
<v Rashid Shams>some sub basins.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9209-0
00:45:53.863 --> 00:45:57.367
<v Rashid Shams>If we categorized losses basin
into different subbasins based</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9209-1
00:45:57.367 --> 00:46:00.644
<v Rashid Shams>on their differences aside
response and we are looking at</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9209-2
00:46:00.644 --> 00:46:04.261
<v Rashid Shams>azimuth based effects and there
is a considerable difference in</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9209-3
00:46:04.261 --> 00:46:06.183
<v Rashid Shams>Sub Basin or basin side
response.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9212-0
00:46:06.193 --> 00:46:08.995
<v Rashid Shams>When we look at events from
different azimuths, especially</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9212-1
00:46:08.995 --> 00:46:11.798
<v Rashid Shams>if you are talking about 9094,
not the, then that is there</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9212-2
00:46:11.798 --> 00:46:13.983
<v Rashid Shams>something interesting that we
are looking at.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9231-0
00:46:13.993 --> 00:46:17.480
<v Rashid Shams>Although we didn't specifically
look at any geometric parameter</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9231-1
00:46:17.480 --> 00:46:20.476
<v Rashid Shams>which was based on azimuth
build, we looked at aspect,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9231-2
00:46:20.476 --> 00:46:23.746
<v Rashid Shams>which was kind of based on
azimuth, but it didn't show what</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9231-3
00:46:23.746 --> 00:46:24.563
<v Rashid Shams>we expected to.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9247-0
00:46:25.293 --> 00:46:28.037
<v Rashid Shams>But you're right, azimuth based
dependency is interesting,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9247-1
00:46:28.037 --> 00:46:30.083
<v Rashid Shams>especially in different parts of
the basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9260-0
00:46:33.963 --> 00:46:37.023
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Alan Young, feel free to unmute
yourself and ask your question</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9260-1
00:46:37.023 --> 00:46:37.363
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>please.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9265-0
00:46:40.563 --> 00:46:41.453
<v Yong, Alan K>Hey, Rashid.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9268-0
00:46:42.163 --> 00:46:43.393
<v Yong, Alan K>Interesting talk.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9301-0
00:46:43.403 --> 00:46:46.735
<v Yong, Alan K>Thank you very much and also
thank you for working on this</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9301-1
00:46:46.735 --> 00:46:50.462
<v Yong, Alan K>based on Edge and based on depth
problem, we really need to get a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9301-2
00:46:50.462 --> 00:46:51.253
<v Yong, Alan K>grasp on this.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9339-0
00:46:53.313 --> 00:46:57.851
<v Yong, Alan K>I have several questions I'm
gonna try to limit them the the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9315-0
00:46:53.933 --> 00:46:54.183
<v Rashid Shams>Thank you.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9339-1
00:46:57.851 --> 00:47:02.464
<v Yong, Alan K>fundamental question I have is
you're using VS30 as the basis</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9339-2
00:47:02.464 --> 00:47:05.143
<v Yong, Alan K>to calculate your residuals,
right?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9358-0
00:47:05.153 --> 00:47:10.503
<v Yong, Alan K>And your residuals are assumed
to be related to based on Edge</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9358-1
00:47:10.503 --> 00:47:12.143
<v Yong, Alan K>and based on depth.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9360-0
00:47:12.153 --> 00:47:12.643
<v Yong, Alan K>Is that correct?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9366-0
00:47:14.483 --> 00:47:14.853
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9368-0
00:47:14.863 --> 00:47:15.333
<v Rashid Shams>Residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9387-0
00:47:15.343 --> 00:47:18.246
<v Rashid Shams>Uh, yeah, we use commotion
model, which is based on VS</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9387-1
00:47:18.246 --> 00:47:19.883
<v Rashid Shams>theory and based in depth both.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9388-0
00:47:20.683 --> 00:47:21.123
<v Yong, Alan K>Right.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9432-0
00:47:21.363 --> 00:47:25.708
<v Yong, Alan K>So the VS30 data that you showed
you showed somewhere along the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9432-1
00:47:25.708 --> 00:47:30.189
<v Yong, Alan K>line you showed the map that was
very dense with a lot of symbols</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9432-2
00:47:30.189 --> 00:47:32.633
<v Yong, Alan K>upside down triangles and all
that.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9446-0
00:47:32.763 --> 00:47:35.713
<v Yong, Alan K>Are those ground motion
recording stations?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9436-0
00:47:32.793 --> 00:47:33.123
<v Rashid Shams>Ohh yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9451-0
00:47:36.463 --> 00:47:38.533
<v Rashid Shams>Or those were just sites in
Socal?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9463-0
00:47:38.623 --> 00:47:40.493
<v Rashid Shams>Yeah, those were ground motion
recording stations.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9482-0
00:47:40.683 --> 00:47:44.913
<v Rashid Shams>So we categorize those ground
motion recording stations into</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9482-1
00:47:44.913 --> 00:47:47.133
<v Rashid Shams>different geomorphic categories.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9495-0
00:47:47.143 --> 00:47:48.003
<v Rashid Shams>I think this was the one.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9492-0
00:47:47.473 --> 00:47:48.743
<v Yong, Alan K>OK, that's the one.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9497-0
00:47:49.023 --> 00:47:49.383
<v Yong, Alan K>So.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9514-0
00:47:49.433 --> 00:47:53.703
<v Yong, Alan K>So these are all ground motion
recording stations, so they.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9512-0
00:47:53.153 --> 00:47:54.163
<v Rashid Shams>Yeah. From NGS.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9517-0
00:47:54.173 --> 00:47:55.053
<v Rashid Shams>Two, yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9518-0
00:47:55.733 --> 00:47:56.263
<v Yong, Alan K>OK.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9534-0
00:47:56.333 --> 00:48:00.521
<v Yong, Alan K>And each one of these stations
have a via sturdy, obviously,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9534-1
00:48:00.521 --> 00:48:00.933
<v Yong, Alan K>right.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9551-0
00:48:00.943 --> 00:48:06.665
<v Yong, Alan K>That's what gone into your GM
and everyone of these, what</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9542-0
00:48:03.533 --> 00:48:03.753
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9551-1
00:48:06.665 --> 00:48:07.553
<v Yong, Alan K>types of?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9562-0
00:48:07.563 --> 00:48:12.053
<v Yong, Alan K>Yes, dirty were the basis for
these station.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9576-0
00:48:12.323 --> 00:48:16.572
<v Yong, Alan K>Are they measured via 30 or are
they VS dirty coming from other</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9576-1
00:48:16.572 --> 00:48:17.103
<v Yong, Alan K>methods?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9623-0
00:48:18.433 --> 00:48:22.198
<v Rashid Shams>So I think uh the majorly the
PS3 that was in the Ng W 2</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9623-1
00:48:22.198 --> 00:48:25.897
<v Rashid Shams>database was from various
methods and it was then there</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9623-2
00:48:25.897 --> 00:48:29.993
<v Rashid Shams>was a selected BSI that were
used for ground motion modeling.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9631-0
00:48:30.163 --> 00:48:31.573
<v Rashid Shams>So we wrapped those VS 30.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9633-0
00:48:31.583 --> 00:48:31.973
<v Rashid Shams>It was.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9668-0
00:48:31.983 --> 00:48:35.191
<v Rashid Shams>There was some measured as well,
and there was some study for the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9668-1
00:48:35.191 --> 00:48:37.864
<v Rashid Shams>sites where there was no
measurement which was I think</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9668-2
00:48:37.864 --> 00:48:38.933
<v Rashid Shams>proxy Bates B3 values.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9677-0
00:48:38.943 --> 00:48:40.323
<v Rashid Shams>So I think it might be a
combination of.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9691-0
00:48:42.363 --> 00:48:44.323
<v Rashid Shams>All those measured and inferred.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9686-0
00:48:42.653 --> 00:48:42.953
<v Yong, Alan K>OK.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9742-0
00:48:45.043 --> 00:48:49.757
<v Yong, Alan K>So I'm I'm I'm I'm kind of
concerned about the uncertainty</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9742-1
00:48:49.757 --> 00:48:54.792
<v Yong, Alan K>in the yesterday itself because
in situ measurement based bias</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9742-2
00:48:54.792 --> 00:48:59.266
<v Yong, Alan K>30 does have uncertainty
depending on the type of VS 30</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9742-3
00:48:59.266 --> 00:49:02.383
<v Yong, Alan K>the type of technique that's
used now.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9785-0
00:49:02.393 --> 00:49:07.103
<v Yong, Alan K>If you're also using infer,
that's to say topographic slope</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9785-1
00:49:07.103 --> 00:49:12.284
<v Yong, Alan K>terrain, whichever you're using,
and they're using these inferred</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9785-2
00:49:12.284 --> 00:49:16.759
<v Yong, Alan K>and and the basis of these
inferences are related to how</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9785-3
00:49:16.759 --> 00:49:17.073
<v Yong, Alan K>you.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9797-0
00:49:18.073 --> 00:49:21.083
<v Yong, Alan K>Uh, partition your basin.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9818-0
00:49:21.353 --> 00:49:26.359
<v Yong, Alan K>You know, there's a there's a
bit of circular effect there,</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9815-0
00:49:25.703 --> 00:49:26.413
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9818-1
00:49:26.359 --> 00:49:27.193
<v Yong, Alan K>right, so.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9869-0
00:49:26.643 --> 00:49:29.970
<v Rashid Shams>Although I most of the sites
that we have here have a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9869-1
00:49:29.970 --> 00:49:33.728
<v Rashid Shams>measured B study, but for the
sites where there was no where</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9869-2
00:49:33.728 --> 00:49:37.302
<v Rashid Shams>study, I think some kind of
inferred V study was selected</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9869-3
00:49:37.302 --> 00:49:38.473
<v Rashid Shams>for modeling, yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9857-0
00:49:37.543 --> 00:49:38.243
<v Yong, Alan K>Right, right.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9871-0
00:49:38.253 --> 00:49:40.383
<v Yong, Alan K>What I'm saying is it'll be
interesting to see.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9874-0
00:49:41.803 --> 00:49:42.293
<v Yong, Alan K>Uh.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9933-0
00:49:42.423 --> 00:49:46.527
<v Yong, Alan K>Which sites are from measured
and which sites are from</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9890-0
00:49:45.393 --> 00:49:45.633
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9933-1
00:49:46.527 --> 00:49:50.707
<v Yong, Alan K>inferred and how the inferred
sites look as you do your</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9933-2
00:49:50.707 --> 00:49:55.184
<v Yong, Alan K>calculation for your basin
effects and then look at how the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9933-3
00:49:55.184 --> 00:49:59.588
<v Yong, Alan K>measured sites look because the
measured sites go into the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9933-4
00:49:59.588 --> 00:50:02.573
<v Yong, Alan K>production for them fired sites,
right?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9932-0
00:50:00.523 --> 00:50:00.733
<v Rashid Shams>Mm-hmm.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9954-0
00:50:02.623 --> 00:50:07.602
<v Yong, Alan K>And the inferred sites use
geometry as part of its means to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9939-0
00:50:02.803 --> 00:50:03.023
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9954-1
00:50:07.602 --> 00:50:09.013
<v Yong, Alan K>predict the S 30.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9963-0
00:50:09.443 --> 00:50:10.743
<v Yong, Alan K>Do you see what I'm saying here?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9976-0
00:50:10.843 --> 00:50:12.003
<v Rashid Shams>Yeah, yeah, yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9965-0
00:50:11.663 --> 00:50:12.073
<v Yong, Alan K>Right.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9983-0
00:50:12.083 --> 00:50:15.383
<v Yong, Alan K>And so if you use VS 30 as a
means to get to your residuals.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9994-0
00:50:17.353 --> 00:50:19.533
<v Yong, Alan K>It gets rather messy there.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/9995-0
00:50:20.493 --> 00:50:21.373
<v Rashid Shams>Yeah, that is correct.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10017-0
00:50:21.383 --> 00:50:24.418
<v Rashid Shams>Yeah, it would be interesting to
look at the inferred whatever</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10017-1
00:50:24.418 --> 00:50:26.923
<v Rashid Shams>sites that we have from that
have inferred bias 30.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10020-0
00:50:28.843 --> 00:50:29.253
<v Yong, Alan K>Right.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10048-0
00:50:30.183 --> 00:50:32.540
<v Yong, Alan K>Yeah, I like I said, I have a
lot of questions, but I'm gonna</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10048-1
00:50:32.540 --> 00:50:33.643
<v Yong, Alan K>just keep it to that for now.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10045-0
00:50:33.903 --> 00:50:34.403
<v Rashid Shams>Yeah, sure.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10049-0
00:50:34.413 --> 00:50:34.833
<v Rashid Shams>No ways.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10053-0
00:50:36.883 --> 00:50:37.243
<v Yong, Alan K>Thank you.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10056-0
00:50:38.063 --> 00:50:38.693
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10064-0
00:50:38.813 --> 00:50:39.123
<v Rashid Shams>Thank you.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10068-0
00:50:39.023 --> 00:50:41.703
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Yes, she thinks that was really
nice talking.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10081-0
00:50:41.713 --> 00:50:43.973
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>I'll echo Alan Sayings an
important topic.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10099-0
00:50:43.983 --> 00:50:46.453
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>So I'm glad you all are looking
at it in so much detail.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10134-0
00:50:47.243 --> 00:50:51.117
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>I in the middle part of your
talk, you were going through all</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10134-1
00:50:51.117 --> 00:50:55.179
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>the parameters and it looked to
me like the distance to the edge</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10134-2
00:50:55.179 --> 00:50:58.803
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>of the base end had a pretty
strong and consistent trend.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10165-0
00:50:59.443 --> 00:51:02.954
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>And I don't know, maybe I'm not
an expert at at looking all</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10165-1
00:51:02.954 --> 00:51:06.114
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>these scatter plots, but to me
that seems like pretty</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10165-2
00:51:06.114 --> 00:51:07.343
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>consistent parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10184-0
00:51:08.163 --> 00:51:12.042
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Umm, but then I noticed you
didn't incorporate that into the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10184-1
00:51:12.042 --> 00:51:12.933
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>model and see.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10185-0
00:51:14.663 --> 00:51:14.903
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10196-0
00:51:16.823 --> 00:51:18.093
<v Rashid Shams>Yeah, there there was some.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10203-0
00:51:17.213 --> 00:51:18.133
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Is there reason?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10205-0
00:51:18.143 --> 00:51:19.723
<v Rashid Shams>Yeah, there there is a good
observation.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10232-0
00:51:19.733 --> 00:51:22.831
<v Rashid Shams>There was some trend we did try
incorporate that parameter</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10232-1
00:51:22.831 --> 00:51:25.510
<v Rashid Shams>initially, but that that
parameter didn't show any</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10232-2
00:51:25.510 --> 00:51:27.033
<v Rashid Shams>appreciable like performance.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10280-0
00:51:27.583 --> 00:51:31.424
<v Rashid Shams>A benefit that we were hoping to
look at, we tried some other</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10280-1
00:51:31.424 --> 00:51:35.265
<v Rashid Shams>parameters that still showed
some trend, but that didn't work</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10280-2
00:51:35.265 --> 00:51:38.920
<v Rashid Shams>out as well, but it did help us
to look at Basin and basin</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10280-3
00:51:38.920 --> 00:51:42.203
<v Rashid Shams>exercises that we further hope
to explore in detail.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10292-0
00:51:42.613 --> 00:51:45.323
<v Rashid Shams>So there is a good observation
that did that.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10327-0
00:51:45.333 --> 00:51:48.912
<v Rashid Shams>Parameter did show some trend
but it didn't work out as well</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10327-1
00:51:48.912 --> 00:51:52.550
<v Rashid Shams>for the that in comparison to
the parameters that we selected</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10327-2
00:51:52.550 --> 00:51:53.313
<v Rashid Shams>for modeling.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10322-0
00:51:54.333 --> 00:51:54.643
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>OK.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10324-0
00:51:54.653 --> 00:51:54.853
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10331-0
00:51:54.863 --> 00:51:55.893
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>So then I had a second question.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10350-0
00:51:55.903 --> 00:52:00.532
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>You were talking about this 2
kilometer kind of distance away</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10353-0
00:52:00.513 --> 00:52:00.733
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10350-1
00:52:00.532 --> 00:52:01.503
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>from the end.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10393-0
00:52:01.593 --> 00:52:05.804
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>I mean, to me it looked maybe
like 3 or 4 kilometers work a</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10393-1
00:52:05.804 --> 00:52:09.946
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>little better, but is that then
correlated with your other</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10393-2
00:52:09.946 --> 00:52:14.438
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>parameters like something about
a radius of a couple kilometers</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10393-3
00:52:14.438 --> 00:52:16.123
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>is influencing the site.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10399-0
00:52:16.133 --> 00:52:17.933
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>So you have that I.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10414-0
00:52:18.003 --> 00:52:23.013
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>I forget that the SA I that the
one I didn't catch.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10409-0
00:52:20.123 --> 00:52:20.343
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10449-0
00:52:23.023 --> 00:52:27.435
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Like what size areas that
related to that kind of two or</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10449-1
00:52:27.435 --> 00:52:31.383
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>three people on their face and
edge kind of thing?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10428-0
00:52:27.563 --> 00:52:27.833
<v Rashid Shams>Yes.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10441-0
00:52:27.843 --> 00:52:29.013
<v Rashid Shams>So the yeah, the.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10461-0
00:52:31.393 --> 00:52:33.563
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Is that inherently kind of
picking that up?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10473-0
00:52:34.123 --> 00:52:37.773
<v Rashid Shams>Yeah, we did not correlate based
in edge with this parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10479-0
00:52:37.783 --> 00:52:39.433
<v Rashid Shams>But yeah, we this parameter.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10492-0
00:52:39.443 --> 00:52:41.646
<v Rashid Shams>I think you were talking about
this parameter which worked</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10492-1
00:52:41.646 --> 00:52:41.833
<v Rashid Shams>well.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10505-0
00:52:42.323 --> 00:52:44.933
<v Rashid Shams>If you look at, yeah, so.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10500-0
00:52:42.573 --> 00:52:42.773
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10518-0
00:52:44.433 --> 00:52:50.130
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>If you go back a slide, I can't
read that there, but like 2500</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10518-1
00:52:50.130 --> 00:52:50.763
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>meters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10520-0
00:52:50.773 --> 00:52:51.223
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>OK.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10541-0
00:52:51.293 --> 00:52:54.350
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>So those two and half dollars,
so you use a circular area</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10541-1
00:52:54.350 --> 00:52:55.773
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>radius of 2 1/2 kilometers.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10552-0
00:52:57.883 --> 00:52:58.093
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10561-0
00:52:57.963 --> 00:53:01.573
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Right to to to define this as a
I.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10591-0
00:53:03.003 --> 00:53:06.534
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>So maybe that's sort of
capturing some of that two to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10566-0
00:53:03.563 --> 00:53:03.833
<v Rashid Shams>Yeah.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10591-1
00:53:06.534 --> 00:53:10.261
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>three kilometer distance away
from the base and edge and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10591-2
00:53:10.261 --> 00:53:10.653
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>thing?</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10594-0
00:53:11.633 --> 00:53:12.663
<v Rashid Shams>Yeah, it could be.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10601-0
00:53:12.673 --> 00:53:13.943
<v Rashid Shams>And yeah, you were right.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10663-0
00:53:13.953 --> 00:53:17.762
<v Rashid Shams>If you look at this plot, you
can see it might look at might</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10663-1
00:53:17.762 --> 00:53:21.633
<v Rashid Shams>look like 2-3 to four or two to
three kilometers, but we also</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10663-2
00:53:21.633 --> 00:53:25.254
<v Rashid Shams>fit like a generic genetic
algorithm based breakpoint and</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10663-3
00:53:25.254 --> 00:53:28.876
<v Rashid Shams>it was kind of consistent with
two kilometers, although 2</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10663-4
00:53:28.876 --> 00:53:31.873
<v Rashid Shams>kilometer is like not a very uh
fixed boundary.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10711-0
00:53:31.883 --> 00:53:35.159
<v Rashid Shams>This is something that we came
up with just like we still have</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10711-1
00:53:35.159 --> 00:53:38.487
<v Rashid Shams>to look into it as in detail and
it's still not very consistent</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10711-2
00:53:38.487 --> 00:53:41.711
<v Rashid Shams>in different parts and it could
change depending on different</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10711-3
00:53:41.711 --> 00:53:43.583
<v Rashid Shams>types of sedimentary basin as
well.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10728-0
00:53:43.883 --> 00:53:46.130
<v Rashid Shams>But it is a good point to
correlate this with the</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10728-1
00:53:46.130 --> 00:53:47.433
<v Rashid Shams>parameters that we looked at.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10740-0
00:53:47.483 --> 00:53:50.753
<v Rashid Shams>That is Siri average and like
2500 meters.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10751-0
00:53:51.003 --> 00:53:51.943
<v Rashid Shams>So it could be interesting.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10760-0
00:53:52.983 --> 00:53:54.493
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>Your face and edge back.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10769-0
00:53:54.503 --> 00:53:56.773
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>A slide also shows a frequency
dependence.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10787-0
00:53:56.783 --> 00:53:59.967
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>So you could consider a
frequency dependent radius to</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10787-1
00:53:59.967 --> 00:54:01.383
<v GS-CAMFT-Bldg19-YosemiteConfRoom2030>your essai or something.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10795-0
00:54:01.933 --> 00:54:04.603
<v Rashid Shams>Yeah, yeah, that is also a good
point.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10803-0
00:54:04.703 --> 00:54:06.373
<v Rashid Shams>Yeah, it does show frequency
dependence.</v>

b0889a18-2f9e-49ed-a1c1-c2b0e584f25a/10816-0
00:54:08.533 --> 00:54:09.283
