We present a new three-dimensional model of the major fault systems in southern California. The model describes the San Andreas fault and associated strikeslip fault systems in the eastern California shear zone and Peninsular Ranges, as well as active blind-thrust and reverse faults in the Los Angeles basin and Transverse Ranges. The model consists of triangulated surface representations (t-surfs) of more than 140 active faults that are defined based on surfaces traces, seismicity, seismic reflection profiles, wells, and geologic cross sections and models. The majority of earthquakes, and more than 95% of the regional seismic moment release, occur along faults represented in the model. This suggests that the model describes a comprehensive set of major earthquake sources in the region. The model serves the Southern California Earthquake Center (SCEC) as a unified resource for physics-based fault systems modeling, strong ground-motion prediction, and probabilistic seismic hazards assessment.

We thank the Southern Californian Earthquake Center (SCEC) for financial and scientific support in this effort. The methods used in constructing the fault model were developed with support of NSF Grant Number 0087648. We also thank students at Harvard who have helped tremendously in developing the model and its supporting database, including P. Fiore, N. Williams, P. Lovely, K. Bergin, J. Doblecki, L. Nousek, A. Larson, and M. Zacchilli. We also offer thanks to D. Kilb and G. Kent at the Scripps Institution of Oceanography Visualization Center, which hosted a workshop to help build and evaluate the CFM.
