Landslides offshore of southern California, 2023 Landslides have been mapped offshore of Southern California. Polygons were mapped from visual interpretation of high-resolution multibeam echosounder data (MBES), single-beam echosounder data, and seismic reflection data.

The offshore region of southern California is a tectonically active area that includes more than 20 fault-bounded basins and ridges that are subject to various types of mass-wasting and landslide processes. The collection of high-resolution seafloor mapping data offshore southern California, mostly within the last 25 years, provide a new data set that forms the basis for the identification and mapping of landslides and slide-related features throughout...

The Quaternary fault map includes mapped geometries and attribute information for offshore fault systems located in California State and Federal waters. The polyline shapefile and matching KML file have been compiled from previously published mapping where relatively dense, high-resolution marine geophysical data exist. The data are accompanied by a PDF containing citations for the compiled source data. Most of the marine geophysical data used for mapping 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...
