2009 Annual Meeting: Source Inversion Validation Workshop

Date: September 13, 2009
Organizers: P. Martin Mai, Morgan Page, Danijel Schorlemmer
Location: Horizon Ballroom, Hilton Palm Springs Resort, Palm Springs, CA

Detailed knowledge about the kinematics of the earthquake source process is critical for inferring rupture dynamics, for building source models for ground-motion simulation, and for studying earthquake mechanics in general. However, source-inversion results for past events exhibit large intra-event variability for models developed by different research teams for the same earthquake. Also, the reliability, resolution, and robustness of the inversion strategies and the obtained rupture models have not received their due attention.

This workshop is a follow-up on two workshops in the past year during which the Source Inversion Validation (SIV) project for earthquake rupture imaging was discussed. We thus particularly invite researchers working in earthquake source inversion and statistical analysts interested in developing a "testing platforms" for the SIV-project. The first part of this workshop will be dedicated to invited lectures. This will be followed by presentations and discussions on the first "testing models", and in particular results from initial Green's function testing. The second part of the workshop will feature presentations and discussions on the infrastructure and implementation of the testing center. Future funding for participating groups will also be discussed. We hope for many dedicated scientists who will devote time and energy into the SIV-project, but we also invite users of source-rupture models and those genuinely interested in earthquake source inversion.
