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.
