Summary

Landslide debris aprons 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.

Purpose

These data were compiled as a part of a USGS effort to understand the geologic processes of mass wasting offshore of Southern California. They are intended to provide baseline knowledge of the geology, geomorphology, and distribution of landslides debris aprons offshore of Southern California, for use by scientists, managers, and the general public. These data can be used with geographic information systems (GIS) software for research purposes.
