Since the 1960's, the California Geological Survey (CGS) has produced numerous maps that show landslide features and delineate potential slope-stability problem areas. Preparation of these maps has been episodic, often driven by landslide disasters and subsequent legislative mandates. Many CGS landslide maps and related products have been produced for local or state agencies in response to their specific needs.
This index includes landslide maps produced over many years for a variety of purposes. See the description of CGS landslide programs for details of some of the major programs and types of landslides and landslide maps.
