Probabilistic seismic hazard analysis for offshore structures in the Santa Barbara Channel phase 2 report
This report summarizes progress through Phase 2 of the probabilistic seismic hazards analysis (PSHA) for the Santa Barbara Channel being carried out by the Lawrence Livermore National Laboratory (LLNL) for the Minerals Management Service (MMS) of the US Department of the Interior. The purpose of the PSHA is to provide a basis for development by MMS of regulations governing evaluation of applications to re-license existing oil platforms in federal waters within the Channel with respect to seismic loading. The final product of the analysis will be hazard maps of ground motion parameters at specified probability levels of exceedence. This report summarizes the characterization of local earthquake sources within the Channel and onshore areas of the Western Transverse Ranges, development of a ground motion attenuation model for the region, and presents preliminary hazard results at three selected sites.
