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.

Post-Fire Debris-Flow Hazards

Topographic map of post-fire debris flow

Estimates of the probability and volume of debris flows that may be produced by a storm in a recently burned area, using a model with characteristics related to basin shape, burn severity, soil properties, and rainfall.

Map showing locations of damaging landslides in Santa Clara County, California, resulting from 1997-98 El Nino rainstorms Map showing locations of damaging landslides in Santa Clara County, California, resulting from 1997-98 El Nino rainstorms

Heavy rainfall associated with a strong El Nino caused over $150 million in landslide damage in the 10-county San Francisco Bay region during the winter and spring of 1998. A team of USGS scientists collected information on landslide locations and damage costs. About $7.6 million in damages were assessed in Santa Clara County.

Map showing locations of damaging landslides in Napa County, California, resulting from 1997-98 El Nino rainstorms Map showing locations of damaging landslides in Napa County, California, resulting from 1997-98 El Nino rainstorms

Heavy rainfall associated with a strong El Nino caused over $150 million in landslide damage in the 10-county San Francisco Bay region during the winter and spring of 1998. A team of USGS scientists collected information on landslide locations and damage costs. Napa County was relatively unaffected in comparison to other counties in the region with approximately $1.1 million in damages...

Map and description of the active part of the Slumgullion Landslide, Hinsdale County, Colorado Map and description of the active part of the Slumgullion Landslide, Hinsdale County, Colorado

This text accompanies a map of many of the features on the active part of the Slumgullion landslide, Hinsdale County, Colo. Long-term movement creates and destroys a variety of structural features on the surface of the landslide including faults, fractures, and folds, as well as basins and ridges. The Slumgullion landslide consists of a large volume of inactive landslide deposits and a...

Map showing 1983 landslides in Utah Map showing 1983 landslides in Utah

The State of Utah sustained direct damages from landslides and flooding in excess of $400 million during approximately three months in the spring of 1983. These disastrous events were declared national disaster areas (Anderson and others, 1985).

Preliminary map showing landslides in Alabama Preliminary map showing landslides in Alabama

This map brings together data from all known reports on landslides in Alabama mentioned by Alger and Brabb (1985) and information provided by State and County Highway Departments in response to a questionnaire sent in 1981 by K. F. Rheams. Additional landslide data from the northern part of the state and from Jefferson County were added by Fred Taylor and E. E. Brabb from reports by...

Map showing landslides in California that have caused fatalities or at least $1,000,000 in damages from 1906 to 1984 Map showing landslides in California that have caused fatalities or at least $1,000,000 in damages from 1906 to 1984

Understanding where landslide processes in California have been most severe is helpful in determining priorities for landslide mapping, mitigation measures, and preparedness planning. Although a few studies of landslide damage and fatalities have been published (see sources of data 12, 17, 34, 36, 40), and many more reports mention landslide damage and fatalities incidentally, our map is...
