EXTREME GROUND MOTION WORKSHOP
Conveners: Tom Hanks and Norm Abrahamson
Extreme Ground Motion Workshop | Agenda
The third annual Extreme Ground Motion (ExGM) Workshop will consist of two
sessions, the first on Saturday afternoon, September 6, 13:00-18:00, and the second on
Sunday morning, September 7, 08:00-12:00. The first session will feature more recent
results than those presented at the Extreme Ground Motion special sessions at the
Seismological Society of America Annual Meeting in April 2008. We will also lay out the
ExGM Endgame as we presently envision it, now that we are three years into the ExGM
Program, with just two remaining before the ExGM Final Report is due.
The Sunday morning session will be devoted to precarious-rock research, as performed
by scientists funded by ExGM at Yucca Mountain and by scientists funded by SCEC in
southern California. The focus will be on turning precarious rocks into real seismic
hazard constraints, which requires both the amplitude of toppling ground motions and
the age for which the rock has been precarious.
