USGS
The National Landslide Information Center (NLIC) is responsible for distributing information about landslides to the lay public, researchers, planners, and local, state, and federal agencies. USGS Scientists are working to reduce long-term losses and casualties from landslide. Landslides occur in all 50 states and are widespread. Landslides disrupt communities and lifelines, transportation corridors, fuel and energy conduits, and communication linkages. The Pacific Coast, the Rocky Mountains, and the Appalachian Mountains are prone to the effects of land sliding. Land slides deaths average from 25-50 lives a year.
