2010 SCEC Annual Meeting: Extreme Ground Motion (ExGM) Workshop: The Last Hurrah

Convener: Tom Hanks, Norm Abrahamson
Date/Time: Saturday, September 11, 2010 (1:30-5:30 pm)
Location: Horizon Ballroom I, Hilton Palm Springs Resort, Palm Springs, CA
Participants: view list of registrants

Apart from the hiatus in 2009, ExGM/SCEC workshops have been part of the SCEC Annual Meeting since 2005, when the ExGM research program began. These workshops have been attended by a large number of scientists of many different interests, in part because of the wide-ranging research supported by ExGM. As of this writing in the first week in August, the Final Report of the ExGM research program is being prepared, and a summary of it will be presented at the workshop. Other presentations will focus on results more recent than the last ExGM/SCEC workshop two years ago. These include progress in the dynamic rupture code validation models and applications, dynamic fragility calculations for PBRs, several dozen new exposure ages determined from the abundance of 36Cl, and a new, more rigorous formalism for the Points In Hazard Space graphic that summarizes so much of the ExGM research.

The Cooperative Agreement with the Department of Energy will end on September 30, 2010, and the ExGM research program as we have known it for the last five years will also end. We do, however, expect that various threads of the ExGM fabric will continue for some time to come. One of these is the Ground Motion Simulation effort, long an important matter for SCEC scientists that has been also supported by ExGM and PG&E. Recent developments in this continuing activity will also be summarized at this workshop.
