Summary of geologic data and development of A Priori Rupture Models for the Elsinore, San Jacinto, and Garlock faults

April 19, 2008

This appendix to the WGCEP Earthquake Rate Model 2 summarizes geologic data and documents the development of the rupture models for the Elsinore, San Jacinto, and Garlock faults. For the summary of available geologic data, the documentation is organized by fault and fault segment and includes a summary of slip rates, event timing and recurrence, slip-per-event, and historical seismicity for each segment. This information is compiled from the published literature as well as newer studies that have not yet been published. For the unpublished data, we either are familiar, having visited the paleoseismic sites, or participated in the data collection, or we have solicited the principal investigators at each site for their latest results. While these unpublished results are preliminary, we have chosen to include them because the results were considered in development of the rupture models and it is unlikely that the sites will be formally published before the WGCEP Earthquake Rate Model is finalized. The second part of this document describes the construction of the rupture models used in the WGCEP Earthquake Rate Model 2, and the rationale that went into the construction of these models, with a summary of what types of data were considered when the rupture models were created.
