The Quaternary fault map includes mapped geometries and attribute information for offshore fault systems located in California State and Federal waters. The polyline shapefile has been compiled from previously published mapping where relatively dense, high-resolution marine geophysical data exist. The data are also available in kml format and are accompanied by a pdf containing citations for the compiled source data. In the last decade, a number of new marine geophysical datasets collected by the U.S. Geological Survey (USGS), the Ocean Exploration Trust, and other organizations has led to substantially improved high-resolution mapping of the seafloor in areas including California's mainland State waters and the southern California continental borderland. Data include comprehensive multibeam bathymetry, seismic-reflection, and marine magnetic data in numerous offshore areas. Most of these data have been processed, merged, and released by the USGS in maps, data releases, and journal publications in support of the California Seafloor Mapping Program and the U.S. West Coast and Alaska Marine Geohazards Project. Improved data coverage has allowed researchers to better map offshore faults in areas previously unmapped or covered only by low-resolution data. Additionally, subsurface imaging and seafloor sampling has led to better understanding of fault kinematics and recency of deformation, which are critical for accurately assessing California's seismic and coastal hazards. Purpose: The geographic information systems (GIS) shapefile presented here contains offshore fault geometries, locations, ages, slip rates, and relevant published reference information (please refer to the rest of the metadata for detailed attribute information and references). This compilation represents a significant update to previous national and regional fault datasets, which have been developed without the benefit of new high-resolution datasets. The geodatabase has been designed for easy ingestion by partners including the California Geological Survey and the USGS Quaternary Fault and Fold Database, and to be used to improve seismic hazards products, especially the USGS National Seismic Hazard Maps, the Uniform California Earthquake Rupture Forecast, and the Southern California Earthquake Center Community Fault Model. Other stakeholders include academic scientists, consultants, community planners and managers, the risk assessment community, and the general public.
