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.

Preliminary photointerpretation map of landslide and other surficial deposits of the Mount Vaca, Vacaville, and parts of Courtland, Davis, Lake Berryessa, and Woodland 15-minute quadrangles, Napa and Solano counties, California Preliminary photointerpretation map of landslide and other surficial deposits of the Mount Vaca, Vacaville, and parts of Courtland, Davis, Lake Berryessa, and Woodland 15-minute quadrangles, Napa and Solano counties, California

This map presents preliminary information about the distribution and general character of landslides and other surficial deposits. When used in combination with other types of information, such as data on soils, bedrock geology, slopes, seismic response, hydrology, vegetation and climatic variation, it should be easier to arrive at sound decisions regarding the physical aspects of land...

Photointerpretive map of landslides and surficial deposits of northernmost Napa County, California Photointerpretive map of landslides and surficial deposits of northernmost Napa County, California

This map shows various types of landslide deposits, scarps, and related topographic features, in addition to other types of surficial deposits, in northernmost Napa County, California. It was prepared by viewing overlapping vertical aerial photographs with a stereoscope. This method allows the geologist to see a three-dimensional model of the terrain to be analyzed and thereby permits...
