2007 Annual Meeting: Extreme Ground Motion Workshop

Organizer: Tom Hanks
Dates: September 8-9
Location: Palm Springs, CA

Description: Extreme ground motions are the very large amplitudes of earthquake ground motions that can arise at very low probabilities of exceedance, as was the case for the 1998 PSHA for Yucca Mountain. The Extreme Ground Motion (ExGM) project investigates the credibility of such ground motions through studies of physical limits to earthquake ground motions, unexceeded ground motions, and frequency of occurrence of very large ground motions or of earthquake source parameters (such as stress drop and faulting displacement) that cause them. The SCEC/ExGM Workshop (Sept 8-9) will review research findings since last September.
