2007 Annual Meeting: SoSAFE Workshop

2007 Annual Meeting: SoSAFE Workshop
Dates: January 8-9, 2007
Location: Andrus Gerontology Center (Room 224); Davidson Conference Center
Organizer: Ken Hudnut

The Southern San Andreas Fault Evaluation (SoSAFE) Project will better define the past 2000 years of earthquake occurrence as well as slip rates on the fault system. One year ago, the initial meeting of SoSAFE set this new SCEC special project in motion. Since that time, new USGS funding and support from the core SCEC budget have combined to allow several important studies to begin along the San Andreas Fault, some results of which will be presented at this workshop. At a science workshop held Jan. 8-9, 2007, to commemorate the great 1857 Fort Tejon earthquake, priorities for the next year were discussed and planning began for an ambitious collaborative proposal. Improvements are being made in event chronologies at key sites, as well as in event correlations between sites, and crucial data gaps along the fault are starting to be filled. Coordinated studies employing novel dating methods emphasize cross-validation of methods and field sampling techniques to gain a better understanding of actual uncertainties in geologically estimated slip rates over time spans of up to several tens of thousands of years. At this year's workshop, further discussion and planning will take place and the SoSAFE investigator community is welcomed to participate and engage in this discussion and planning work.

14:40 Discussion Topics:
  • Tuning and finalizing the Mw7.8 scenario event slip distribution, fault geometry, etc.
  • What to do in case of no SoSAFE funds (or various levels of cuts) in FY07? (definitely will need to recommend priority of work and funding levels to the SCEC Planning Committee for Jan. 15 mtg.)
  • How broad can SoSAFE afford to be? Must we focus on 'A1' SCEC Science Priority Objective?
  • What are scientific priorities of this community?
  • What group resources are needed? (e.g., travel support for field coordination, computers to make use of B4 Project LIDAR data, geochronology sample preparation facilities, shoring, other?)
 
16:45 Confirm future meeting dates, and go around the room
