GeoFEST (at Open Channel Foundation) -
uses stress-displacement finite elements to model stress and flow in a realistic model of the Earth's crust and upper mantle in a complex region such as the Los Angeles Basin. The model includes stress and strain due to the elastic response to an earthquake event in the region of the slipping fault, the time-dependent viscoelastic relaxation, and the net effects from a series of earthquakes. The physical domain may be two or three dimensional and may contain heterogeneous materials and an arbitrary network of faults.

PARK (at servogrid server) -
a boundary element program that determines the stress on every element of the fault surface due to slip on every other element, using a Green's function approach. For example, it can be used to compute the history of slip, slip velocity, and stress on a vertical strike-slip fault that results from using state-of-the-art rate and state frictional constitutive laws on the fault for a specific geographic setting at Parkfield, California.

Virtual California (at servogrid server) -
a code that utilizes the Monte Carlo method in order to generate simulated, realistic earthquakes on an arbitrary fault surface mesh. It uses topologically realistic networks of independent fault segments that are mediated by elastic interactions. These segments can be designed to represent fault systems spanning the region of California.
