Synthetic Seismic and GPS Data from Nov 13, 2008 ShakeOut Exercise
The SCEDC is now distributing a subset of seismograms (20 km and 40 km spacing) and GPS data computed for the 2008 ShakeOut scenario. See maps below for spatial distribution.
Background:
The ShakeOut exercise of Nov 13, 2008 involved the simulation of a
magnitude 7.8 earthquake on the southern San Andreas Fault the
propagated north to Tejon Pass. The estimates of damage were based
on a simulation that is decribed in Graves et al
(2008).
ShakeOut scenario was developed by the USGS Multi Hazards Demonstration
Project in partnership with the California Geological Survey,
Southern California Earthquake Center and many other partners with
funding from the USGS, CGS, and FEMA.
Funding for the ShakeOut simulations was provided by SCEC under NSF grants EAR-0623704
and OCI-0749313 and by the US Geological Survey. The largescale simulations were run
at
USC’s Center for High Performance Computing and Communications
under an agreement with the SCEC CME project.

Seismic Datasets:
The computational grid samples the wavefield every 2 km. Packages
of seisomgrams
are output in 3 collections: sampled every 40 km (66 stations), sampled
every 20 km (242 stations), and sampled at site that are nearly
colocated with continuous GPS sites (77 stations).
