The researchers are processing and analyzing these results. It allows us for the first time to get to the level of detail we need to realistically simulate the frequencies that do the most damage. Our target application, the entire Greater Los Angeles Basin, is an order of magnitude larger and must be run for multiple scenarios to assess the seismic hazard. The expanded capability of the CRAY T3E gives us hope that this problem is within reach. Animation of a simulated earthquake in the San Fernando valley.

The simulation covered a 54 x 33 kilometer area, superimposed here on a satellite view of topography, to a depth of 15 km. Los Angeles can be seen in the southeast corner.
