Brawley Seismic Zone Simulations
Brawley Seismic Zone Simulations
Summary
As part of SCEC's computational geophysics research activities, Christos Kyriakopoulos, at the Center for Earthquake Research and Information (CERI), ran Dynamic Rupture simulations for the Brawley Seismic Zone (BSZ) Region in southern California that combine numerical models with a broad spectrum of geophysical information, such us tectonic deformation maps measured by Global Positioning System (GPS) and Synthetic Aperture Radar Interferometry (InSAR), seismic tomography, and other geological data.

Figure caption
Map (left panels) and 3D (right panels) view of supercomputer earthquake simulations in the Brawley Seismic Zone, CA. The figure shows how different stress conditions affect rupture propagation across the complex network of faults. The top panels show a high-stress case scenario (leading to very fast rupture propagation, higher than the S wave speed) while the bottom panels show a medium stress case simulation.
