WEBVTT 00:00:00.000 --> 00:00:05.000 No. 00:00:05.000 --> 00:00:21.000 Welcome back from break, everyone. Thank you for coming. Now we have so many exciting things happening in Northern California we have to do a series of quick file updates from all of our major stakeholders and to take us through this tour of exciting happenings, we have 00:00:21.000 --> 00:00:22.000 Anne Wein. 00:00:22.000 --> 00:00:31.000 Hi, everyone. [giggle] Thank you, Sarah. Okay, well, we're going to kick off with Nicole Mendoza from the Safety Seismic Commission, California 00:00:31.000 --> 00:00:36.000 Office of Emergency Services. 00:00:36.000 --> 00:00:42.000 Thank you, Anne. Thank you also, Sarah and USGS for the opportunity. 00:00:42.000 --> 00:00:51.000 As Anne said, my name is Nicole Mendoza and I am the program manager for the Seismic Safety Commission anchored at Cal OES. 00:00:51.000 --> 00:01:08.000 The big update that I have for you today is in co-sponsorship with partners at Cal OES, CGS, FEMA, and USGS, amongst several others, we actually are going to hold an "Earthquake and Climate Change" workshop. 00:01:08.000 --> 00:01:14.000 The purpose is to share information amongst the scientific community and other stakeholders 00:01:14.000 --> 00:01:26.000 to identify available research and knowledge gaps. Originally, it was scheduled for March 4th and 5th. However, it has been postponed to the week of May 12th. 00:01:26.000 --> 00:01:37.000 More information to come as we finalize those dates. If you would like to be on the distribution list, please do send me an email. My email address will be in the next slide. 00:01:37.000 --> 00:01:48.000 What we're looking at is two-half day sessions. Both of them will be in the morning. They will cover several in-depth topics and we will have moderators. 00:01:48.000 --> 00:02:18.000 The speakers include CGS, USGS, PG&E, East Bay Mud, SoCal Edison, UC Berkeley, Microsoft AI for Good, SCEC, Caltrans, FEMA Region 9. We are working to solidify those speakers for the May dates. If there are no questions right now. I'm also happy to answer questions in the chat. Yes, in person and virtual. So we will have a 00:02:18.000 --> 00:02:36.000 small space for some in-person attendance but virtual is our goal for everyone to be virtual. John's actually going to be hosting us so that is one of the good things is we'll have someone who's already experienced with these workshop 00:02:36.000 --> 00:02:46.000 hosting. So if there are questions, pop them in the chat and I'm happy to answer them. Otherwise, if you are interested in being on the distribution list. 00:02:46.000 --> 00:02:55.000 My email address, nicole.mendoza@caloes.ca.gov. And thank you for the time. 00:02:55.000 --> 00:03:06.000 Thank you, Nicole. Sounds exciting. We'll move on to Heidi Tremaine with the Earthquake Engineering Research Institute. 00:03:06.000 --> 00:03:14.000 Hi there! Yes, I'm Heidi Tremaine. I'm the executive director at the Earthquake Engineering Research Institute and we appreciate the invitation here. 00:03:14.000 --> 00:03:20.000 For those who aren't aware, the Earthquake Engineering Research Institute is a nonprofit organization 00:03:20.000 --> 00:03:27.000 of members who are dedicated to understanding earthquake risk and increasing earthquake resilience in communities worldwide. 00:03:27.000 --> 00:03:36.000 We do that through a whole bunch of activities that we host that help our members grow their technical knowledge and share it, 00:03:36.000 --> 00:03:40.000 that develop their leadership and advocacy skills, expand their collaborative networks 00:03:40.000 --> 00:03:53.000 and really grow their multidisciplinary context to the topic of earthquakes. I think a key highlight of EERI is that we're trying to bring together many perspectives and viewpoints, many different disciplines, 00:03:53.000 --> 00:04:03.000 of course, with engineering as in our title, but we have many members who contribute and participate from earth science all the way through to public health. 00:04:03.000 --> 00:04:09.000 So we're pleased to have as many people contribute to our mission as possible. 00:04:09.000 --> 00:04:23.000 [Let me get my slide.] One of our key programs and the ways that we do this is called the "Learning from Earthquakes Program." Many of you may be aware, but this is our flagship program that conducts earthquake reconnaissance after a major 00:04:23.000 --> 00:04:35.000 earthquake around the world. Its goal is to accelerate and increase learning from earthquake-induced disasters looking at the built environment as well as the social context and community context 00:04:35.000 --> 00:04:41.000 that is affected by the earthquakes themselves. We gather multidisciplinary teams together, 00:04:41.000 --> 00:04:47.000 and of academics, practitioners, and put them in the field to help bring back lessons for the rest of us, 00:04:47.000 --> 00:04:53.000 so that we can grow both our professional practice and introduce new research questions and needs. 00:04:53.000 --> 00:05:09.000 The EERI in this role, we also serve as the vice chair of the California Earthquake Clearinghouse, and we partner with many other states in the deployment and development of their clearinghouse plans. You're going to hear a little bit more of that in a later sessions by Maggie Ortiz Milan, who's the leader of our staff team, 00:05:09.000 --> 00:05:19.000 who works with that. I also want to shout out, I think on today's call, I saw Eduardo Miranda, who is the chair of our "Learning for Earthquakes" program, along with Michael Miller from ARUP. 00:05:19.000 --> 00:05:26.000 I'm not sure if I saw Michael on today, but definitely Eduardo is here. So I'm sure he's able to answer questions 00:05:26.000 --> 00:05:38.000 as well. Kind of one new feature of learning from earthquakes that I wanted to highlight of kind of the new and upcoming things that we have going is that we are forming some new subcommittees in 2025. 00:05:38.000 --> 00:05:44.000 These are topical based committees that we're trying to bring people from many disciplines together to collectively look at them. 00:05:44.000 --> 00:05:57.000 These new committees will have a charge like many of our others. Anne Wine actually happens to chair one of our others that looks at business resilience and how businesses are impacted by earthquakes. We also have a public health committee that's very active right now as well. 00:05:57.000 --> 00:06:05.000 We're looking to grow some new committees in the topics of lifelines, housing, tsunami, and as well as risk and insurance. 00:06:05.000 --> 00:06:17.000 And the idea of these committees is that it worked to develop a reconnaissance agenda and set priorities for what needs to be studied after future earthquakes. When earthquakes happen, they advise on what the needs are and whether we should deploy, what activities should take place. 00:06:17.000 --> 00:06:28.000 As those earthquakes happen, they work to develop topic-focused products with findings and lessons from those events. And that is through a variety of mechanism tools, internal and external to EERI. 00:06:28.000 --> 00:06:38.000 We have our virtual earthquake reconnaissance team reports that might do quick investigations all the way to detailed earthquake spectra, our technical journal 00:06:38.000 --> 00:06:50.000 sessions, special collections or papers. So I have a huge range of activities that we do and we want to promote and share those findings within our membership, but of course, well beyond and external to our group as well. 00:06:50.000 --> 00:06:59.000 So if anyone's interested in joining one of these committees, as I said, we want people from all different aspects interested in this and bringing their technical expertise to it. 00:06:59.000 --> 00:07:17.000 We are going to be hosting some workshops to develop some reconnaissance agendas and kickstart some of these new committees. And if you're interested, contact Maggie. Her email address is on here and you can find it in the slides later. She's also on the call today, so you can also send her a chat message too. 00:07:17.000 --> 00:07:25.000 Another key activity that we do to share findings at EERI and help our members connect to each other and learn from each other is our journal Earthquake Spectra. 00:07:25.000 --> 00:07:43.000 So EERI has had this journal for many decades now. And here are some new findings that you're aware of. Our November issue was released back in 2024, but our February issue is coming out momentarily. I was hoping it was live online. I checked earlier today, but it's not yet live yet, but it should be in the next day or so. 00:07:43.000 --> 00:07:57.000 We have many different topics and disciplines covered by our journal, and so there's always interesting research to find there. I encourage you to consider submitting offering to support peer review. There's a lot of ways to get involved. 00:07:57.000 --> 00:08:02.000 Two other important collections that we've developed recently I really wanted to highlight here. 00:08:02.000 --> 00:08:21.000 The first is related to the 2023 Turkey earthquakes. We've developed an entire collection. I want to credit our current editor, which is Jack Baker, and our editor in chief and then our editor as well, Helen Crowley. Both of them have helped work with a whole series of guest editors 00:08:21.000 --> 00:08:34.000 who conducted reconnaissance and leaders within Turkey itself to develop a collection of articles. Thanks to everyone who submitted papers. There's about 30 articles now that are published live and ready for viewing and you can see them at our website 00:08:34.000 --> 00:08:57.000 here. If you type earthquakespector.org, it redirects you and that's kind of the easiest path to get there. We also partnered closely with the USGS and for the 2023 update for the National Seismic Hazard Model. So there's a special collection up there too. We did do some announcements about some of the papers, the Mark Peterson paper, but there's many more in that collection 00:08:57.000 --> 00:09:10.000 that have been posted live, a few more coming through, and we're going to do a big rollout of that soon. But I encourage you to visit the website to see more there. And I want to thank everyone on the USGS team for your collaboration on that one. 00:09:10.000 --> 00:09:21.000 Very appreciated. I think it's going to be a great resource for all of us in our community from earth science all the way through to our engineering colleagues. 00:09:21.000 --> 00:09:31.000 Another event that we have coming up and activity is our National Conference on Earthquake Engineering. This is a broad conference. The name is Earthquake Engineering, but we consider it much like we consider the Earthquake Engineering in EERI. 00:09:31.000 --> 00:09:49.000 Pretty broad and covering all disciplines. I was just before this call at 10 o'clock on a call So don't tell everyone I wasn't on the AI detailed study, but I was on a call with our organizing committee that is developing the program for this conference and they're really excited to get going, excited to share. We're going to have a call for papers. 00:09:49.000 --> 00:10:03.000 Coming up very soon, most likely uh most I think in February or March, so very soon. We encourage all of you to submit. Oh, and I'm going to correct myself. It's a call for papers will come up this summer for individual abstracts and we're doing short 00:10:03.000 --> 00:10:20.000 papers, so only about four pages, but we're going to also do a call for special sessions. So those of you with research topics or kind of some ideas from this workshop that you want to share further and explore again next summer. We encourage you to develop special session proposals and that call is going to be coming out soon, 00:10:20.000 --> 00:10:29.000 also, individual papers are welcome soon. So we hope to see many of you in Portland and joining in that collaborative experience. 00:10:29.000 --> 00:10:48.000 There's a few other activities I wanted to highlight that I thought would be particularly relevant to this Northern California, maybe and beyond audience. The first is that on February 11th, we have a reconnaissance webinar coming up. This is a joint team from learning on earthquakes and the 00:10:48.000 --> 00:11:13.000 social science earthquake or extreme events response group. So both of us doing a joint team reconnaissance went to Turkey recently, kind of in a follow-up study back in the fall to look at how the recovery has been developing, what new findings they're learning from those in the community, and check the progress of the recovery there. And so I encourage you to register. The link is here. I think Maggie can put in the chat. If not, I'll put it in the chat when we're done. 00:11:13.000 --> 00:11:17.000 But I encourage you to register in attendance just in a few weeks. 00:11:17.000 --> 00:11:39.000 We also have recently released an oral history on Robert Olson he was the leader of the California Seismic Safety Commission, and so there's a lot of interesting historical knowledge about his role and shaping some of California's policy and legislative efforts, a very interesting 00:11:39.000 --> 00:11:42.000 take on his life and work and I encourage you to review that there. 00:11:42.000 --> 00:12:02.000 And we also are planning a next generation liquefaction research project, a workshop most likely up in Oakland in the spring. So we're working on finalizing a date and a venue for that. So keep an eye out for that. And then finally, we also have several Northern California regional chapters, one for Northern California that really covers the Bay Area primarily. 00:12:02.000 --> 00:12:16.000 And then we also have a regional chapter in Sacramento. Both of them host local events and are looking to have more members participate and be involved. So I encourage you to check those out and consider next time you see an announcement joining one of their events. 00:12:16.000 --> 00:12:44.000 I think I'm at the end here, but I just want to encourage you to think about joining EERI. We encourage members and colleagues to participate and you can learn more about what we have going on and how you can participate, lend your expertise to what we're doing and work with all of us together to make communities safer from earthquakes in the future. So I encourage you to join. We also have a collaborative membership with the Seismological Society of America. So if you're a member there, there's also an add-on option there 00:12:44.000 --> 00:12:57.000 and I encourage you to learn more and participate. So with that, Anne, I think back to you and I'm happy to answer questions throughout the session. 00:12:57.000 --> 00:13:02.000 That's fantastic. Lots going on. Thanks, Heidi. And great to hear about the new committees. 00:13:02.000 --> 00:13:13.000 So next up is Tim Melbourne with the Central Washington University, he's going to tell us more about the Cascadia Region Earthquake Science Center. 00:13:13.000 --> 00:13:34.000 All right. Good morning, everybody. Thanks for the invitation to give me an overview of this. So yeah, I'm Tim Melbourne from CWU. I will provide a brief overview of the Cascadia Region Earthquake Science Center, CRESCENT for short. And CRESCENT is a triple pun, so if you don't know what that is, I'll leave it to you as a homework to figure out what the other two 00:13:34.000 --> 00:13:53.000 meanings are on CRESCENT all geologic in origin. So CRESCENT is a current NSF funded center, it's a five years, so we're into the second year now. It's anchored at the University of Oregon, Diego Melgar is the PI. 00:13:53.000 --> 00:14:05.000 There's six staff associated with it and a bunch of sort of senior personnel leading different aspects of it from over a dozen universities, USGS and a bunch of other organizations. 00:14:05.000 --> 00:14:16.000 And so when you get into this sort of type of center, we've basically broken it out into three central pillars. Or what we would call basic and applied science. 00:14:16.000 --> 00:14:34.000 There is what we call partnership and applications pillar, which is the idea that as the science moves along, we need to get that message out to industrial partners, to communities, to those who can plan, and then there's a geoscience education and inclusion component where 00:14:34.000 --> 00:14:47.000 trying to bring in more people and vastly expand sort of the breadth of people who are working on Cascadia, relevant tectonic, earthquakes, tsunami, etc. Problems 00:14:47.000 --> 00:14:55.000 such that the working body of people kind of reflects and looks like the people who live here and are involved in it. 00:14:55.000 --> 00:15:01.000 So those are the three science pillars. Let me just kind of break them out for you. 00:15:01.000 --> 00:15:21.000 One-on-one. So the key science questions are you know, everything you already know related to sort of how tectonics of the subduction zone drives tectonic hazards how is strain accumulated and released throughout the earthquake cycle. You probably know Cascadia is extremely rich that way with 00:15:21.000 --> 00:15:31.000 lots and lots of slow slip events, lots of history of big events documented in the paleoseismic record, 00:15:31.000 --> 00:15:38.000 excellent instrumentation. So how can we break that into looking at the temporal and spatial variability of all the past earthquakes that we know, 00:15:38.000 --> 00:15:45.000 what controls are there in rupture dynamics during megathrust events? Can we tease those out of the record 00:15:45.000 --> 00:15:57.000 or from modern genetic measurements, anything like that. What are the hazards that all of those produce, not just from the interplate earthquake, but also crust and the deep events in the subducting slabs. 00:15:57.000 --> 00:16:05.000 What is the nature of the strong ground motion in the Cascadia subduction zone? How do the basins impact that, etc., etc. And then, of course, 00:16:05.000 --> 00:16:12.000 when we have the big megathrust of earthquakes, we have the big tsunamis and there's a very rich record of that. 00:16:12.000 --> 00:16:20.000 So that's kind of the science, overarching science questions that live under the science pillar, if you will. 00:16:20.000 --> 00:16:37.000 And so to kind of get a handle on that, we've broken these science things that we're interested in into essentially six working groups and then also some special interest groups, which I'll talk about in a moment. But the working groups are 00:16:37.000 --> 00:16:56.000 designed around producing specific products for like, for example, a community velocity model along with all the ways to interface it. So different entities working on different pieces can contribute to it. We'll need that for all kinds of things from simulating strong ground motion and basin coupling and all that stuff. 00:16:56.000 --> 00:17:07.000 So same thing with faults. We have a community fault model. Amanda Thomas is one of the Co-PIs and she's, well, actually, she just moved to UC Davis, but she's still doing a bunch of the stuff. 00:17:07.000 --> 00:17:22.000 She spearheaded the development of some really fascinating and really cool bleeding edge, three-dimensional exploratoriums for these CDM and community fault models. So you can check those out, I mean, they're really neat. 00:17:22.000 --> 00:17:29.000 I've wasted a lot of time just zooming through all of the fault structures and all that, so it's really quite neat. 00:17:29.000 --> 00:17:40.000 Another working group is what we call DET, dynamic ruptures, earthquake cycles, and tsunami models. So how does seismogenic rupture nucleate propagate? 00:17:40.000 --> 00:17:47.000 How does this happen if we can repeat it and model it over thousands of cycles? What does that mean for tsunami genesis? 00:17:47.000 --> 00:17:53.000 In that case, one of the defined products is a catalog of ruptures and tsunami run-ups and whatnot. 00:17:53.000 --> 00:18:03.000 Another working group is, we call it C3S coupling slow slip and seismicity. This is the Frankenstein group. I'm not in charge of it. I'm part of it. 00:18:03.000 --> 00:18:22.000 You would think these are all wrapped up in each other. And so when we were justifying this scientifically, I can tell you, for instance, in Ellensburg, Washington, where my university is on the east slope of the North Cascades, the biggest tectonic signal we see is what we think is elastic strain from the subduction zone, right. 00:18:22.000 --> 00:18:40.000 And if you go over to the west side of the mountains, you see the same thing, but it gets changed by the slow slip events that are happening very frequently and we think we have enough knowledge about that that if you want to talk about generating, say, a crustal block model, 00:18:40.000 --> 00:18:59.000 And you have geodesy, you have 500-600 stations up here that many have been running for 30 years, you have very good long-term constraints, but you have to correct those long-term constraints for upwards of 20% to 25%, depending on where you are on what the slow slip events are doing, because that's the last, right. So these things are all 00:18:59.000 --> 00:19:13.000 conjoined, if you will, and teasing them out, we decided required that they all of the issues be put into one working group. So that's one I know a lot about. The Coastal Paleoseismology, CPAL for short, is the last one, when, where. 00:19:13.000 --> 00:19:26.000 When were the past earthquakes? How large were they? What kind of tsunamis? So we can tease that out of looking at all of the paleoseismic evidence that can be found, microfossils, tree rings, 00:19:26.000 --> 00:19:43.000 run-up rack lines, all that stuff. So that's the CPAL group. And then we have these what we call special interest groups and these are kind of, think of these as seed working groups, proto working groups, where we know this is really important. We couldn't 00:19:43.000 --> 00:20:01.000 There wasn't enough room in the budget at least this round, but we have groups working on it. So offshore observations, ground motion modeling, fluids modeling, ground failure like landslides we know when you have lots of evidence that when you have the big mega structures 00:20:01.000 --> 00:20:21.000 you have many, many landslides. Those are big things so we have these special interest groups, and if you're interested in any sort of this, these are very easy because they're somewhat informal, they're a very easy way to get involved. And if you want to get involved, there's some emails. You can email me or there's lots of 00:20:21.000 --> 00:20:31.000 emails at the end here. So that's the science side. The GEI side, we have a bunch of programs going. 00:20:31.000 --> 00:20:52.000 C-case is one where we're mixing up at the high school level between indigenous communities and non-indigenous communities. We have this twinning program, which we are currently recruiting mentors for so that's where an undergrad as two mentors, one at their institution and one at another institution who's doing something that that mentor is involved with. 00:20:52.000 --> 00:21:13.000 So if I were to advise one, I could be the remote one working on, say, Geodesy in Cascadia, and then there's another mentor at an undergraduate at some other university where we're providing a certain level of guidance. We have cores to code, which is really interesting. So you go out and the students go out and they sample cores, they can actually see the cores. 00:21:13.000 --> 00:21:26.000 And then you can run models that the cores that are recording either past run-ups or subsidence or whatever, then you can run like the Okada-type models that then drive inundation models and compare them all together. So that's been very popular so far. 00:21:26.000 --> 00:21:42.000 We have some fellowships. And then a series of technical short courses for using kind of modern day, like for examples in the GPS world, Jupiter notebooks to teach how to think about analyzing geodetic time series. 00:21:42.000 --> 00:21:57.000 But the same things for all the different disciplines that are covered, and then the third pillar is partnerships and applications. And the idea is that as the scientists, we like to do our science, but it can get very siloized and 00:21:57.000 --> 00:22:18.000 if there are new paradigms, new models that need to be known by industrial partners, PG&E, for instance, it should be a very clear conduit, and so when we set about designing this system, we really wanted to have the center 00:22:18.000 --> 00:22:23.000 be as connected into industrial partnerships, communities, all of that as we could. 00:22:23.000 --> 00:22:38.000 We've had a number of sort of relationship building exercises that have gone on in our first 18 months. There's an annual partnerships and applications meeting. And the next one is scheduled for June of 2025 in Portland; 00:22:38.000 --> 00:23:04.000 there's Cascadia Lifelines; there's a newsletter that goes out. Other public engagements and meetings within the working groups to coordinate activities and make them relevant to and sort of community partners. So if this is of interest to any of you in any fashion, get in touch. We take all comers. We're very interested. I mean, part of our mission is to 00:23:04.000 --> 00:23:09.000 build the community and bring as many people in as we can. 00:23:09.000 --> 00:23:18.000 So you can screenshot this. You can take the QR code. You can email me. You can email Andy Cliff or Shannon Fasola at University of Oregon. 00:23:18.000 --> 00:23:24.000 Cascadia quakes will be answered by somebody. That's a promise. And then we're active on social media. 00:23:24.000 --> 00:23:29.000 So I think I'm about over time, so I will stop there. Thank you. 00:23:29.000 --> 00:23:37.000 Yeah, thank you, Tim. Very comprehensive. Over to Greg Beroza from Stanford who's talking about the Southern California Earthquake Center. 00:23:37.000 --> 00:23:44.000 Yeah, thanks, Anne. And thanks to all of you for the opportunity. So I'll give a brief update. No slides. 00:23:44.000 --> 00:24:01.000 About SCEC. So most of you are familiar with SCEC, I think, but we've evolved significantly in the last year plus. The "S" now stands for statewide, and that's a change in our geographic scope and brings with it new scientific opportunities. 00:24:01.000 --> 00:24:15.000 So SCEC is funded by NSF and USGS primarily, but with other important sources of support from PG&E, DOE, FEMA, NASA, and others. And we're very grateful, of course, for the study and continuing support we get from the USGS. 00:24:15.000 --> 00:24:34.000 So we collaborate across academia, government, and the private sector develop a better understanding of earthquakes and how they work that can be translated into useful and actionable information for reducing the risk from earthquakes. So our goals are very much aligned 00:24:34.000 --> 00:24:43.000 with the strategic goals and strategic actions that are articulated in the USGS's recent decadal plan. 00:24:43.000 --> 00:24:59.000 Part of our, with becoming a statewide center, we've also reorganized to refresh the leadership and more broadly distribute the science leadership and also to the extent that possible, try to streamline it. 00:24:59.000 --> 00:25:11.000 We have this convening capability that we use to bring together the academic community in particular, those who are concerned with earthquakes, 00:25:11.000 --> 00:25:32.000 and we play a role that USGS used to play decades ago in their topical redbook conferences of getting together a small working groups to pursue particular problems so one nice example of that is the USGS SCEC Community Stress Stop Validation Project. 00:25:32.000 --> 00:25:48.000 That's a project that is global in its participation, it's extremely active and there are over 25 papers I just heard this morning that are already accepted for a special issue in BSSA 00:25:48.000 --> 00:25:54.000 that document and archive the progress that have been made under that initiative. 00:25:54.000 --> 00:26:09.000 So as many of you know, we have a science plan in which we recruit small pilot projects each year. We had a very vigorous response to that this year, and we're in the process of finalizing the collaboration plan, which is the subset of those that are 00:26:09.000 --> 00:26:28.000 recommended for support. In doing that, we recognize that we've had a a focus for decades on Southern California, but the new geographic reach of the center means that we are placing a greater emphasis on the new areas and particularly 00:26:28.000 --> 00:26:49.000 for this workshop, Northern California, and this manifests in efforts to extend community models to have a statewide extent, so we'll hear a little later on from Scott Marshall about the different community models. There's a statewide community fault model, community geodetic model, 00:26:49.000 --> 00:27:06.000 the velocity model is not there yet, and we're making efforts towards building that. And one of them is to be able to merge multi-scale velocity models. There'll be a workshop soon to be announced in April on that topic, but that would provide the sort of foundational support 00:27:06.000 --> 00:27:26.000 towards developing a statewide community velocity model. Another thing that SCEC does is to acquire and deploy high performance computing capability to earthquake science problems that are of interest to the USGS and SCEC, of course and this includes 00:27:26.000 --> 00:27:41.000 most notably Cyberashake, which we've used to construct hazard curves for 315 sites in the greater San Francisco Bay Area, and I think you're going to hear from Todd Callahan about that effort also a little bit later. 00:27:41.000 --> 00:28:07.000 SCEC's working to extend the disciplinary extent or reach and to broaden the availability of research computing. There was last week or the week before, I've lost track, there was a QuakeWorks workshop from which recorded presentations will be available soon. And that was in the service of sort of broadening participation in HPC. 00:28:07.000 --> 00:28:14.000 So we're making earthquake catalogs more uniform in terms of magnitude, more complete in terms of focal mechanisms. 00:28:14.000 --> 00:28:26.000 We're working towards the next generation of earthquake catalog based on machine learning that will span the West Coast of the U.S., so it will include and it's collaborative with CRESCENT. 00:28:26.000 --> 00:28:32.000 So from the Canadian border to the Mexican border, there are going to be billions of phase picks that go into this. 00:28:32.000 --> 00:28:49.000 And we're going to find millions of earthquakes and it's really going to transform our view of the plate boundary. And there's already clear indications of that in the Mendocino triple junction where these earthquake catalogs show really astonishingly detailed and complex 00:28:49.000 --> 00:29:05.000 structures that are not previously seen. So we collaborate with CRESCENT and multiple areas, for example, to leverage our longstanding approaches to community model development. 00:29:05.000 --> 00:29:25.000 And curation and their discussions about developing further synergies by joining forces for things like high performance computing allocation requests and proposals in areas of joint interest like the Mendocino Triple Junction. So I'll stop there and take Any comments or questions? 00:29:25.000 --> 00:29:40.000 Thank you, Greg. Yes. Very much. So I think we've got, I don't know, Brad Agard wants to chime in on his recent report about community models. 00:29:40.000 --> 00:29:46.000 If not, Sarah. 00:29:46.000 --> 00:29:50.000 Well, I am loathe to do it because Brad is the one who's doing all of the work, 00:29:50.000 --> 00:30:05.000 but we had a recent model following out of, I think, two years ago, the NorCal workshop, having a a joint meeting between everyone at SCEC and everybody at USGS and all the stakeholders who contribute to all the community models 00:30:05.000 --> 00:30:10.000 to talk about the future of community modeling, how we move forward, how we merge existing ones, what we want them to do in the future. 00:30:10.000 --> 00:30:26.000 All the things with community modeling. Brad has been leading the write-up of the report. It is in internal review at the moment. It is in revision, post a round of internal review it should be done with that soon and submitted into the wider world soon. 00:30:26.000 --> 00:30:27.000 So yay, Brad. 00:30:27.000 --> 00:30:42.000 Okay, thanks, Sarah. We don't have much time for questions, but Heidi, I don't think I saw you had been able to respond to the question about "what kind of time commitments are expected to be on one of the topic 00:30:42.000 --> 00:30:44.000 Committees. Oh, okay. 00:30:44.000 --> 00:30:57.000 I did add it in the chat, but it might be too far up now, but we expect that our learning from earthquake subcommittees would meet about once a month via Zoom. 00:30:57.000 --> 00:30:58.000 Yeah. 00:30:58.000 --> 00:31:07.000 And so for a typical committee member, one to two hours a month, maybe a little more as we ramp up some off out of meeting cycle review, but it shouldn't be too heavy of a lift so encourage you to get involved. 00:31:07.000 --> 00:31:11.000 And I guess it can vary too with what the committee is doing. 00:31:11.000 --> 00:31:12.000 Right. Especially at the beginning though, I think that sounds good, my experience. 00:31:12.000 --> 00:31:17.000 Yeah. 00:31:17.000 --> 00:31:26.000 All right. I wondered about, Nicole, if you would like to share a little bit more about what the tentative sessions are for the climate and earthquake workshop. 00:31:26.000 --> 00:31:27.000 That we have coming up. 00:31:27.000 --> 00:31:57.000 Absolutely. My pleasure. So I'm going to go over just our high level session titles since those are locked in and confirmed. The speakers are subject to change. We did recently have to move the date due to some of the emergency response that's happening in California right now. But so day one right now is looking at a keynote, which would be an overview of the effects of climate change on earthquake hazards, including critical areas of concern for California. 00:31:59.000 --> 00:32:14.000 That would include two sessions in that morning, the impact on climate change on earthquake hazards, and then session two is scheduled to be the intersectionality of cascading risks with climate change mitigation. 00:32:14.000 --> 00:32:23.000 And then for day two, we would be looking at the first keynote being a multi-hazard damage assessment. 00:32:23.000 --> 00:32:38.000 Session three would be research data sets, tools, and scenarios. Session four will be co-adaptive mitigation and funding. And then there will be a closing keynote fire following earthquakes. 00:32:38.000 --> 00:32:48.000 And then a closing session will be an open discussion on cascading hazards induced by climate change. 00:32:48.000 --> 00:32:49.000 It's a full range of It's much more than what the title may suggest. 00:32:49.000 --> 00:32:56.000 A packed agenda. Yes. 00:32:56.000 --> 00:33:04.000 And will people be, I guess we could send the notification of the meeting out through this meeting distribution list is to follow up. Yeah. 00:33:04.000 --> 00:33:25.000 Absolutely. Yeah. If anyone has distribution lists, we will be sending a save the date within the next two weeks once we are able to confirm the actual dates in May. So a save the date will be coming soon. There's also a website that's in the works. So we hope to have those all up within the next week or two. 00:33:25.000 --> 00:33:32.000 So that registration can begin. But a save the date will be going out within the next week. 00:33:32.000 --> 00:33:36.000 Good. Do any of our speakers have any final comments they want to make? 00:33:36.000 --> 00:33:46.000 I don't think I see any more questions. We're going to be wrapping up in a few minutes. 00:33:46.000 --> 00:33:52.000 Okay. And I think we have concluded our updates. 00:33:52.000 --> 00:33:57.000 Thank you so much, Anne and Nicole and Heidi and Tim and Greg. That was great. 00:33:57.000 --> 00:34:03.000 I don't want to keep people from their lunch any longer. So let's all go chew on what they said while we chew on our lunch. 00:34:03.000 --> 00:34:10.000 Everybody except for Scott 1, Scott 2, Vila, Debbie, Evan, and Audi. 00:34:10.000 --> 00:34:23.000 For you people, please come back at say 1245 so we can test your microphone and video before we get started at one. Everybody else come back at one. And when you come back at one, what do you tell us to do? 00:34:23.000 --> 00:34:29.000 Okay, happy lunch, everyone.
