2023 SCEC Annual Meeting

Home

The Southern California Earthquake Center (SCEC) is funded by cooperative agreements with the National Science Foundation (NSF) and the U.S. Geological Survey (USGS) to develop a comprehensive understanding of earthquakes in Southern California and elsewhere, and to communicate useful knowledge for reducing earthquake risk and improving community resilience. Additional support for SCEC activities is provided by the Pacific Gas & Electric Company (PG&E), Department of Energy (DOE), National Aeronautics and Space Administration (NASA), Federal Emergency Management Agency (FEMA), California Governor's Office of Emergency Services (Cal OES), and other partnerships.

We return to Palm Springs on September 10-12 for the 2023 SCEC Annual Meeting!

The program will celebrate the accomplishments of the “Southern” California Earthquake Center and set priorities for SCEC’s broader focus on the transform plate boundary as the “Statewide” California Earthquake Center. The plenary sessions will consist of invited talks, followed by moderated discussions to engage the community in the new efforts and initiatives by SCEC on the themes listed below. The community is welcome to provide input on future directions for the Center and share their results and activities through poster presentations

NOTE: All meeting times below are Pacific Daylight Time (PDT or UTC-7).

CIG Workshop: 2023 Part II. Crafting Quality Research Software and Navigating Publication in Software Journals
Ever wonder how and where to publish your software? The Computational Infrastructure for Geodynamics (CIG) is offering a two-part workshop series designed to equip researchers and developers with the skills and understanding necessary to produce robust, maintainable, and impactful research software. Part I (August 10) covers elements of software development and offers insights into the process of publishing research software in leading software journals. Part II (September 9) is an in-person hack event with help from experts for teams committed to preparing their software for submission. You must register and attend Part I to be eligible to attend Part II. See the CIG event website to register for these events.

Sunday, September 10

09:00 - 11:45	EarthScope-SCEC Workshop: 2023 Rupture and Fault Zone Observatory The Rupture and Fault Zone Observatory (RuFZO) is a community-driven effort that aims to collect geophysical data within rupture zones of significant earthquakes before, during and after major earthquakes (including in the long interseismic periods), and develop the workforce needed to design, build, and operate related geoscience facilities. This workshop will allow for in-person discussions of the RuFZO initiative and will lead to improved plans. The results will be conveyed to the community. Please see the EarthScope event page for more information and to register.
10:00 - 14:00	SCEC Annual Meeting Check-In, Hilton Lobby
14:00 - 15:30	Session 1: State of SCEC Moderators: Greg Beroza, Tran Huynh This session officially kicks off the annual meeting proceedings. The SCEC Director and agency representatives will inform the community about the state of SCEC and of future directions as SCEC fully transitions to the “Statewide California Earthquake Center'' at the end of 2023. We will also hear about SCEC’s Communication, Education, and Outreach recent activities and new initiatives. State of SCEC from the Director (Yehuda Ben-Zion) Remarks from SCEC Sponsors Communication, Education, & Outreach (Mark Benthien, Gaby Noriega)
16:00 - 17:30	Session 2: Going Beyond the Southern California Earthquake Center Moderator: Tim Dawson This session will highlight the accomplishments and advances during SCEC5 (2017-2023). We take this opportunity to recognize the many contributions by the SCEC community and their enduring legacy. The session will close with the popular Distinguished Lecture to inspire us to look ahead. These ideas will continue to be discussed throughout the meeting days, as the SCEC community sets priorities for the coming year. SCEC: Where have we been? Where are we going? (Greg Beroza) Distinguished Lecturer: Ray Weldon, How expanding SCEC and starting CRESCENT will accelerate our understanding of faulting and related hazards

08:00 - 09:30	Session 3: What is the relevance of the earthquakes in Türkiye for California? Moderators: Jon Stewart, Mike Oskin The widespread devastation and loss of life caused by the recent earthquakes in Türkiye underscores an urgent need to understand the risks posed by large earthquakes in California. Similar‐sized earthquakes over a century ago, and the exposure to seismic risk in California has dramatically increased, and continues to rise. This session will focus on what has been learned from the earthquakes in Türkiye and how that might inform earthquake science and engineering in California.

13:00 - 14:30	Session 4: How do earthquakes and fault development coevolve, and how does that impact seismic hazard analysis? Moderators: Ahmed Elbanna, Heather Savage The coupled evolution of earthquakes and faults is an emerging focus area that spans the many disciplines of earthquake science. This session focuses on the observations and modeling required to test novel physics-based models for this coupled evolution, and explores the possible implications for seismic hazard analysis. Yehuda Ben-Zion, Coupled Evolution of Earthquakes, Faults, and Seismic Motion Yihe Huang, Understanding the coevolution of earthquakes and fault damage zones: Implications on earthquake source physics and fault zone structure
15:00 - 16:30	Session 5: How do we bridge scales from the laboratory to the field? Moderators: Eric Dunham, Sylvain Barbot Earthquakes at depth are remote from direct observations. Laboratory experiments can inform the understanding of the physics of faulting in the Earth, but they are carried out at length scales that are at least an order of magnitude smaller than even small earthquakes. This session focuses on how we can bridge scales from the laboratory to the Earth to understand earthquake processes.

Moderators: Brad Aagaard, Lorraine Hwang Community Earth models that codify and share knowledge on different manifestations of the earthquake system have been a hallmark achievement of SCEC. This session explores the opportunities and challenges faced in the continuing improvement and evolution of these models, including their extension beyond their original geographical domain to Northern California and Western Nevada.

SCEC has seen tremendous benefit from high performance computing. This session will address the question of how modeling capabilities need to continue to evolve to meet the challenge of understanding earthquakes.
