Map showing inventory and regional susceptibility for Holocene debris flows and related fast moving landslides in the conterminous United States: Raster data

Debris flows, debris avalanches, mud flows and lahars are fast-moving landslides that occur in a wide variety of environments throughout the world. They are particularly dangerous to life and property because they move quickly, destroy objects in their p

Map showing inventory and regional susceptibility for Holocene debris flows and related fast moving landslides in the conterminous United States: vector data

Debris flows, debris avalanches, mud flows and lahars are fast-moving landslides that occur in a wide variety of environments throughout the world. They are particularly dangerous to life and property because they move quickly, destroy objects in their p

Map and map database of susceptibility to slope failure by sliding and earthflow in the Oakland area, California

Map data that predict the varying likelihood of landsliding can help public agencies make informed decisions on land use and zoning. This map, prepared in a geographic information system from a statistical model, estimates the relative likelihood of loca

Possible Costs Associated with Investigating and Mitigating Some Geologic Hazards in Rural Parts of San Mateo County, California

This publication addresses deep-seated landslide susceptibility, debris flow susceptibility, and other geologic hazards in rural parts of western San Mateo County. The report also estimates possible costs of investigating and mitigating the landslide haz

Landslide initiation locations in Nicaragua

We present an inventory of the initiation locations of landslides triggered by the passage of Hurricane Mitch, October 21-31, 1998 in seven study areas in Nicaragua. The inventory was compiled from aerial photographs and field mapping. Most (perhaps 95%

Landslides triggered by Hurricane Mitch in Nicaragua

We present an inventory of landslides and related downchannel effects triggered by the passage of Hurricane Mitch, October 21-31, 1998 in seven study areas in Nicaragua. The inventory was compiled from aerial photographs and field mapping. Most (perhaps
