Virtual Quake (formerly Virtual California) is a computer simulation which models the earthquake fault system in California. It uses field observations to define fault topology, long-term slip rates and frictional parameters. The faults are meshed into fault-segments and quasi-static elastic interactions are calculated between these segments. Slip is then applied to each segment at geologically-observed rates until stress values exceed the frictional parameters. At this point the segment will break and transfer stress to the rest of the system via the quasi-static interactions described above. Under the correct conditions, transferred stress results in propagating ruptures throughout the system, i.e. a simulated earthquake. The design of Virtual Quake allows for fast execution so many thousands of events can be generated over very long simulated time periods. The result is a rich dataset from which to study the statistical properties of the rupturing fault system.
