Workshop on Use of UCERF3 in the USGS National Seismic Hazard Maps #2

Date: 
Thursday, February 21, 2013
Conveners: 
Mark Petersen and Ned Field
Location: 
USGS Menlo Park Campus

We will present the current state of the WGCEP’s UCERF3 time-independent model (http://www.wgcep.org), and to gauge consensus on its applicability for use in the 2014 update of the USGS National Seismic Hazard Map (NSHM; http://earthquake.usgs.gov/hazards). Much of the methodological details of the UCERF3 model was covered at the October 2012 workshop. Thus, this meeting will focus primarily on changes to earthquake rates and their implications for seismic hazard.

There is no cost to attend the workshop, and it is open to all. Please note that this is a scientific working meeting, and not focused on policy or outreach issues.
