Costly Regional Landslide Events in the United States
What this map layer shows: Fifteen landslides in the United States and Puerto Rico, with the number of deaths associated with these events ranges from none to 150 and the associated costs range from $10 million to $800 million.
Background Information
Sample Map Landslides are the downward and outward movement of earth materials on a slope. This movement generally involves the falling, sliding, or flowing of rock and (or) soil or a combination of these and other less common types of movement. Causes include earthquakes, reservoir drawdowns, heavy precipitation, and floods. Costly regional landslide events are those where there was loss of human life or damage to public or private property. The limits shown in this map layer indicate the extent of extensive landsliding triggered by a single meteorological or seismic event. The extent boundaries were drawn from the published literature and should be considered approximate. In several cases, the limits shown represent an arbitrary administrative boundary, such as a county boundary, rather than the extent of landsliding related to a storm or an earthquake. This map layer was compiled by the U.S. Geological Survey National Landslide Hazards Program (NLHP). The NLHP gathers information, conducts research, responds to emergencies and disasters, and produces scientific reports and other products for a variety of users. The primary objective of the NLHP is to reduce long-term losses from landslides by improving our understanding of the causes of ground failure and suggesting ways to lessen damages and loss of life. The Costly Regional Landslide Events in the United States data set shows 15 landslide events in the United States and Puerto Rico. The number of deaths associated with these events ranges from none to 150, and the associated costs range from $10 million to $800 million. Descriptive information includes the type of landslide, the process that triggered the landslide, location, date, number of deaths, and damages in millions of dollars. Further information on landslides is available from the USGS Landslide Hazards page, and from the National Atlas Landslides page.
