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!

OVERVIEW: The central goal of the SoSAFE (Southern San Andreas Fault Evaluation) project was to increase knowledge of the occurrence and size of earthquakes along the southern San Andreas Fault (SAF) and San Jacinto Fault (SJF) over the last 2000 years. When SoSAFE began ca. 2006, only two published paleoseismic records, Wrightwood and Pallett Creek, extended greater than 1000 years. Since the beginning of SCEC4 five years ago, many paleoseismic investigations have been initiated and/or published by SoSAFE investigators, greatly increasing the number of sites with long records and estimates of paleoslip. With more data have come greater interpretive challenges and a view of more variable recurrence along these major faults of Southern California.  

The purpose of this workshop is: (1) to communicate the latest methods and data that have improved our knowledge and (2) to investigate new approaches and enhance collaborations needed to advance paleoseismic investigations on the SAF/SJF system. The workshop will be structured with a set of morning presentations focused on variations in the signature of slip on the plate boundary system.  The afternoon will be split into two sessions, the first will explore how paleoenvironmental data can be used to leverage paleoseismic sequences, and the second will work to improve coordination between paleoseismic data and modeling approaches such as the Collaboratory for Interseismic Simulation and Modeling (CISM).
