2013 SCEC Source Inversion Validation Workshop

Conveners: P. Martin Mai, Danijel Schorlemmer, and Morgan Page
Dates: September 8, 2013 (08:00-12:00)
Location: Hilton Palm Springs Resort, Palm Springs, CA
SCEC Award and Report: 13116

SUMMARY: In the 2013 Source Inversion Validation (SIV) workshop we presented results on the benchmarks for the M7 normal-faulting ruptures, one of which is embedded in a 3D heterogeneous Earth model that leads to seismic scattering and hence uncertain Green's functions. Effects of uncertain Earth structure on earthquake source inversions were discussed in the context of teleseismic data and their use for source imaging. Teleseismic source inversions were the main focus of this SIV workshop. One goal of the workshop was to then design a first benchmark exercise for teleseismic source modeling. Such a benchmark will also help to address the question of how to quantitatively reconcile back-projection results with tele seismic rupture models.
