The National GEM project consists of a group of Geoscientists, physicists and computer scientists working on new approaches to modeling the onset of earthquakes as the fundamental physics of interacting fault
segments. This involves novel parallel algorithms and high performance oject oriented computing. We have conducted a workshop devoted to study of the possibility of developing the computational capability to carry out large scale numerical simu
lations of the physics of earthquakes in southern California and elsewhere. These simulations would produce detailed temporal and spatial patterns of earthquakes, surface deformation and gravity changes,seismicity, stress as well as, in principle, o
ther variables, including pore fluid and thermal changes, for comparison to field and laboratory data. To construct of the simulations, a state-of-the-art problem solving environment must be developed that will facilitate:
- Construction of numerical and computational algorithms and specific environment(s) needed to carry out large scale simulations of these nonlinear physical processes over a geographically distri
buted, heterogeneous computing network; and
- Development of a testbed for earthquake "forecasting" and "prediction" methodologies which
