Workshop on Distribution of Slip in Large Earthquakes

Date: 
Saturday, June 11, 2011
Conveners: 
Bruce Shaw, Glenn Biasi, Ray Weldon, & Tom Parsons
Location: 
Embassy Suites Mandalay Beach, Oxnard, CA

This workshop will address the following: a) slip distribution along strike, especially when multiple faults are involved; b) slip distribution down dip and whether larger events penetrate deeper (important for resolving current mag-area discrepancies); and c) theoretical and observational constraints on the propensity for ruptures to jump from one fault to another.
