Incorporating Geodetic Data into UCERF3

Thursday, April 1, 2010 - Friday, April 2, 2010
Kellogg West Conference Center, Pomona, CA

The purpose of the workshop is to begin scientific consideration of how to incorporate GPS constraints on strain rates and fault slip rates into the next generation California earthquake hazard assessment ("UCERF3"). A principal outcome of the meeting will be (1) an assessment of secure science ready for UCERF3 applications, and (2) an agenda of new research objectives for SCEC in support of UCERF3 and related probabilistic hazard assessments.

The format of the workshop includes three topical sessions, with limited number of invited presentations scheduled and lots of open discussion time, and an evening poster session. Time is allotted for groups to discuss main scientific issues:

  • Earthquake cycle deformation and influence of postseismic transients
  • Strain rate map methodologies and issues
  • Block modeling methodologies and GPS fault slip rate estimation
  • Reconciliation of differing GPS fault slip and strain rate estimates

All participants were requested to submit poster presentation. A small number of short (~5 minute) presentations were solicited from the submitted poster abstracts.

Actual (e.g. SCEC CMM4 GPS field) or synthetic test data sets were distributed prior to the workshop for modeling test cases. Kinematic and dynamical fault modelers, strain rate mappers, and block modelers thus were able to run their codes to supply outputs for discussion at the workshop.
