Workshop on Use of UCERF3 in the USGS National Seismic Hazard Maps #1

Date: 
Wednesday, October 17, 2012 - Thursday, October 18, 2012
Conveners: 
Mark Petersen and Ned Field
Location: 
Pacific Research Center, Newark, CA

We are hosting a workshop to address the time-independent component of the next Uniform California Earthquake Rupture Forecast, version 3 (UCERF3) on October 17-18 at Pacific Research Center, Dumberton Conference Room (2nd Floor), 7677 Gateway Blvd, Newark, CA 94560 (http://www.pacificresearchcenter.com/). The meeting will begin at 8:00am on the 17th and end at noon on the 18th (with a meeting on deformation models following the next day and a half). Achieving two of the goals with UCERF3 (relaxing segmentation and including multi-fault ruptures) has required significant changes in how the model is constructed.  We will therefore give an overview of UCERF3 modeling framework, present current results, discuss some issues with both the data and methodology, and solicit feedback on how to best resolve these issues before finalizing UCERF3.  Unlike past workshops, this one will not address ground motion prediction equations, as these will be the topic of a later workshop.
