Maps

The Landslide Hazards Program produces maps indicating both historical landslide locations and potential future landslide risks. These maps are typically paired with geospatial data products, which help assess hazard levels, and can be useful for risk-reduction and land-use planning.

Preliminary photointerpretation map of landslide and other surficial deposits of the Concord 15-minute quadrangle and the Oakland West, Richmond, and part of the San Quentin 7 1/2-minute quadrangles, Contra Costa and Alameda Counties, California

This map presents preliminary information about one aspect of the physical environment necessary to sound land-use planning- the nature and distribution of surficial deposits. Because surficial deposits are common and well developed in much of the bay region, it is useful to know how and why they have formed, as well as what properties they possess. When maps like this are used in...

Map showing landslides and areas of potential landsliding in the Salina quadrangle, Utah

The term “landslide” is broadly defined as any “downward and outward movement of slope-forming materials composed of natural rock, soils, artificial fills, or combinations of these materials. The moving mass may proceed by any one of three principal types of movement: falling, sliding, or flossing, or by their combinations” (Varnes, 1958). Landslides and areas of potential landslides are...

Landslide susceptibility in San Mateo County, California

Information on areas susceptible to failure by landsliding is available in many general geologic maps and reports. However, it is commonly presented in complex, technical language, together with data not connected with slope stability. This derivative map is intended to convey such information in nontechnical form so that it will be intelligible to the non-geologist. It portrays only...
