ShakeOut 2013 Response Planning

SCEC's research computing group used the ShakeOut 2013 event to practice creating useful earthquake and seismic hazard information for the SCEC community immediately after a large California event. We identified a series of digital data products that we can calculate using the software and system tools at SCEC, and posted the results on a SCEC wiki a soon as the results were available. We used one of the Northridge Near You event definitions, a scenario earthquake description for a San Bernardino M6.85, as the earthquake information available to us after a big event.
