SCEC Workshop Planned on Earthquake Stress Triggering

SCEC and the USGS are sponsoring a two-day conference on "Earthquake Stress Triggering, Fault Interaction, and Frictional Failure" on June 8-10 in Carmel, CA, convened by Ross Stein of the USGS. The 50-person workshop will focus on earthquake stress transfer and its influence on seismicity in southern California and elsewhere. The goals are to develop common resources for stress-transfer investigations (earthquake catalogs, secular stress models, dislocation and boundary element applications); to examine cases of fault interaction in the seismic, historic, and paleoseismic record; to explore frictional models that might explain these phenomena; and to test the success of such models in explaining earthquake occurrence. The cost, with meals and lodging, will be about $400. Persons interested in attending should contact Ross through his conference coordinator, Nancy Sandoval, at nsandoval@usgs.gov.
