00:00:01.200 --> 00:00:04.720
Hi. I’m Cindy Pridmore, senior
engineering geologist at the California

00:00:04.720 --> 00:00:09.120
Geological Survey, and I work within
the Seismic Hazards Mapping Program.

00:00:09.120 --> 00:00:12.216
I’m also chair of the California
Earthquake Clearinghouse.

00:00:12.240 --> 00:00:15.680
I’ll be talking about California
Geological Survey and the California

00:00:15.680 --> 00:00:19.310
Post-Earthquake Clearinghouse
earthquake response.

00:00:20.320 --> 00:00:22.800
The California Geological
Survey, during an emergency,

00:00:22.800 --> 00:00:25.680
operates according to the
state emergency plan.

00:00:25.680 --> 00:00:29.440
The specific functions are defined
under a memorandum of agreement

00:00:29.440 --> 00:00:32.240
between CGS and the
California Office of Emergency

00:00:32.240 --> 00:00:36.536
Services established under the
authority of an executive order.

00:00:36.560 --> 00:00:41.840
The MOA states that the CGS is to
provide geotechnical data and advice to

00:00:41.840 --> 00:00:46.160
Cal OES regarding natural hazards in
support of emergency planning and

00:00:46.160 --> 00:00:52.296
information support as required during
the state disaster response operations.

00:00:52.320 --> 00:00:56.400
CGS coordinates its emergency
response with other state, local,

00:00:56.400 --> 00:01:00.160
academic, and private entities
and coordinates investigations

00:01:00.160 --> 00:01:04.709
with the USGS under a
memorandum of understanding.

00:01:06.720 --> 00:01:10.520
Following an earthquake or other
natural hazard, CGS may set up

00:01:10.520 --> 00:01:14.696
an emergency operations center
and/or an event information center.

00:01:14.720 --> 00:01:18.640
The EOC facilitates coordination
of CGS response and provides

00:01:18.640 --> 00:01:22.696
geohazard info to the Cal OES
State Operations Center.

00:01:22.720 --> 00:01:27.496
The EIC serves as a hub for exchange
of geoscience information.

00:01:27.520 --> 00:01:30.560
When the California Earthquake
Clearinghouse is activated,

00:01:30.560 --> 00:01:35.729
it basically functions
as the CGS EOC and EIC.

00:01:36.880 --> 00:01:40.320
For earthquake response, CGS has
northern and southern California

00:01:40.320 --> 00:01:44.616
earthquake response team leads
for surface rupture, landslide,

00:01:44.640 --> 00:01:49.134
liquefaction, tsunami,
and volcanic events.

00:01:49.920 --> 00:01:55.071
The CGS team lead coordinates
with the corresponding USGS lead.

00:01:56.000 --> 00:01:57.760
I’ll talk a little bit now
about the California

00:01:57.760 --> 00:02:00.536
Post-Earthquake
Clearinghouse response.

00:02:00.560 --> 00:02:04.480
The clearinghouse is jointly managed
by CGS, which serves as the chair,

00:02:04.480 --> 00:02:09.120
which is myself; EERI, which serves
as the co-chair, occupied by Maggie

00:02:09.120 --> 00:02:14.776
Ortiz-Millan; Cal OES; USGS; and the
California Seismic Safety Commission.

00:02:14.800 --> 00:02:19.120
A physical location close to the
event is usually chosen for the

00:02:19.120 --> 00:02:22.720
California Earthquake Clearinghouse
site, providing a temporary place

00:02:22.720 --> 00:02:24.880
that supports coordination
and the collection of

00:02:24.880 --> 00:02:27.496
critical perishable
information and data.

00:02:27.520 --> 00:02:30.880
It provides the opportunity for agencies
and researchers in the field to

00:02:30.880 --> 00:02:35.680
coordinate reconnaissance efforts,
manage access to restricted areas,

00:02:35.680 --> 00:02:39.256
request overflights
and share findings.

00:02:39.280 --> 00:02:43.200
Who participates at the clearinghouse?
Basically geologists, geophysicists,

00:02:43.200 --> 00:02:47.120
engineers, geotechnical engineers,
social scientists, private consultants,

00:02:47.120 --> 00:02:51.700
and others who conduct post-
earthquake-related investigations.

00:02:53.280 --> 00:02:56.720
The California Earthquake
Clearinghouse activates when an urban

00:02:56.720 --> 00:03:01.016
area is struck by a damaging earthquake
that has a magnitude 6 or greater

00:03:01.040 --> 00:03:06.080
or upon recommendation of the
managing members – CGS, USGS,

00:03:06.080 --> 00:03:09.920
EERI, Cal OES, and Seismic Safety
Commission – when the magnitude

00:03:09.920 --> 00:03:13.816
threshold is not met
but damage is significant.

00:03:13.840 --> 00:03:18.240
It can also activate in a remote
less densely populated area

00:03:18.240 --> 00:03:20.080
when the earthquake
is large enough –

00:03:20.080 --> 00:03:23.988
large enough to damage
structures and lifelines.

00:03:27.680 --> 00:03:31.680
CGS and USGS coordinate their field
response to support the rapid delivery

00:03:31.680 --> 00:03:35.656
of hazard information to the
California State Operations Center

00:03:35.680 --> 00:03:40.560
in support of emergency response.
Esri Field Maps is the data acquisition

00:03:40.560 --> 00:03:45.442
application used by
USGS and CGS field teams.

00:03:46.480 --> 00:03:49.600
We communicate in a variety of
ways at the – at the clearinghouse.

00:03:49.600 --> 00:03:54.960
You can come to the clearinghouse site.
Ridgecrest was staffed over 12 hours

00:03:54.960 --> 00:03:57.200
a day, so usually there was
someone to come in the morning,

00:03:57.200 --> 00:04:00.776
in the late afternoon,
and early evening to speak with.

00:04:00.800 --> 00:04:03.600
The clearinghouse – the physical
clearinghouse provides the

00:04:03.600 --> 00:04:07.096
opportunity for you to
connect with other researchers.

00:04:07.120 --> 00:04:09.840
You can come and get
loaded with the Field Map app

00:04:09.840 --> 00:04:12.296
if you don’t have
that already.

00:04:12.320 --> 00:04:16.400
We can provide suggestions to
investigate if you are coming in and

00:04:16.400 --> 00:04:19.200
you don’t have a place to map,
but you’re a scientist and

00:04:19.200 --> 00:04:22.000
you want to help out.
We can either connect you with

00:04:22.000 --> 00:04:27.016
another team or provide you with
some ideas on what you’d like to do.

00:04:27.040 --> 00:04:30.320
We also provide the opportunity to
volunteer with the clearinghouse

00:04:30.320 --> 00:04:33.360
activities, and this is often
helpful if we have students arriving.

00:04:33.360 --> 00:04:35.520
We can actually put them
to work and support the work

00:04:35.520 --> 00:04:39.190
we’re doing at the
physical clearinghouse.

00:04:40.240 --> 00:04:42.800
One of the most important
communications we have

00:04:42.800 --> 00:04:46.000
are the evening briefings.
You can be in person or remote.

00:04:46.000 --> 00:04:48.080
The picture over
on the left shows

00:04:48.080 --> 00:04:51.496
one of the evening briefings
at the Ridgecrest site.

00:04:51.520 --> 00:04:55.600
The daily field summaries and critical
findings are shared out to a broader

00:04:55.600 --> 00:04:59.840
group of interested parties, and it also 
allows for those off-site to share updates

00:04:59.840 --> 00:05:05.576
and critical information, such as
a new release of satellite imagery.

00:05:05.600 --> 00:05:09.520
The briefings also inform the 24-hour
Cal OES earthquake hazard duty

00:05:09.520 --> 00:05:13.976
officers and the state emergency
operations center at the SOC.

00:05:14.000 --> 00:05:16.480
Critical information
is shared outward from the SOC

00:05:16.480 --> 00:05:19.759
to regional and local
emergency management.

00:05:22.000 --> 00:05:26.776
We also communicate
outwards utilizing the EERI

00:05:26.800 --> 00:05:31.360
LearningFromEarthquakes.org website.
Individual teams can post information

00:05:31.360 --> 00:05:34.880
on recently released data, maps,
photos, reconnaissance reports,

00:05:34.880 --> 00:05:39.760
links to imagery, building performance
reviews, a variety of reports.

00:05:39.760 --> 00:05:44.480
And EERI also provides information
on a variety of ways to be involved

00:05:44.480 --> 00:05:48.000
remotely. We actually have
students working off-site looking

00:05:48.000 --> 00:05:51.360
for information that’s coming out
and being posted on the web,

00:05:51.360 --> 00:05:55.918
and we’re connecting
those reports as well.

00:05:56.560 --> 00:05:59.680
Over on the right, you can see
what the LearningFromEarthquakes

00:05:59.680 --> 00:06:03.280
event resources page looks like.
You can’t really see the details,

00:06:03.280 --> 00:06:08.400
but this is where we posted
our earliest PDF of the fault rupture

00:06:08.400 --> 00:06:12.960
and associated KMZ files. This map
actually came out about four days after

00:06:12.960 --> 00:06:18.121
the event. Future events, I think we’ll
be getting it out a lot more sooner.

00:06:20.800 --> 00:06:24.720
You can find out about when the
clearinghouse is activated after there’s

00:06:24.720 --> 00:06:26.640
been an earthquake and you’re
wondering, oh gee, is there –

00:06:26.640 --> 00:06:30.080
is there going to be a clearinghouse.
That information gets posted

00:06:30.080 --> 00:06:33.280
on the California Earthquake
Clearinghouse-dot-org website.

00:06:33.280 --> 00:06:36.536
So you go there.
You can see the information,

00:06:36.560 --> 00:06:39.416
the location, and
when we’ll be there.

00:06:39.440 --> 00:06:43.440
You can also join the mailing list,
which is on the arrival page when you

00:06:43.440 --> 00:06:46.400
first click on California Earthquake
Clearinghouse, it’s right there.

00:06:46.400 --> 00:06:50.480
And that way, you can be notified
automatically of when and where

00:06:50.480 --> 00:06:53.760
the clearinghouse is activating.
And you can also go to the

00:06:53.760 --> 00:06:57.280
LearningFromEarthquakes.org
website, which I just mentioned,

00:06:57.280 --> 00:07:01.840
and it’ll have the activation
and location posted as well.

00:07:03.680 --> 00:07:05.604
Thank you.
