Workshop on Instrumental & Historical Seismicity in UCERF3
Date:
Friday, June 10, 2011
Conveners:
Andy Michael, Karen Felzer, Ned Field, Dave Jackson, & Tom Parsons
Location:
Embassy Suites Mandalay Beach, Oxnard, CA This workshop will review issues and proposed solutions with respect to the historical and instrumental earthquake catalogs, with particular emphasis on how this influences: a) the association of events to specific faults; b) inferred temporal variations in earthquake rates; and c) regional magnitude-frequency distribution estimates. This workshop will also address best practices for estimating the spatial distributions of a-values, maximum magnitudes, and focal mechanisms for background seismicity (events off our explicitly modeled faults).
