Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

SCEC Community Workshop: Community Stress Model

Conveners: Jeanne Hardebeck, Brad Aagaard, Thorsten Becker, David Sandwell, Bruce Shaw, and John Shaw
Date: October 27, 2014
Location: Kellogg West Conference Center, Pomona, CA (Hillside East Rooms 1 and 2)
SCEC Award and Report: 14024

OVERVIEW: The fourth annual workshop of the SCEC Community Stress Model (CSM) project focused on (1) incorporating the stress predicted by physics-based models into the CSM, and (2) new sources of data to inform and validate CSM models. The workshop format included formal presentations on recent progress in physics-based modeling and data compilation, and focused discussion on the future direction of the CSM.

PARTICIPANTS (23 total, 3 remote): Brad Aagaard (USGS), Thorsten Becker (USC), Peter Bird (UCLA), Michele Cooke (UMass Amherst), Thomas Goebel (Caltech), Jeanne Hardebeck (USGS), Egill Hauksson (Caltech), Liz Hearn (Consulting Geophysicist), Tran Huynh (USC), Nadia Lapusta (Caltech), Eric Lindsey (UCSD), Karen Luttrell (LSU), Patricia Persaud (Caltech), Fred Pollitz (USGS), Margarita Segou (GeoAzur/CNRS), Bruce Shaw (Columbia), Peter Shearer (UCSD), Debbie Smith (USGS), Bridget Smith-Konter (Hawaii), Joann Stock (Caltech), Wayne Thatcher (USGS), Wenzheng Yang (AIR Worldwide), and Jiyang Ye (Missouri)
