Costly Regional Landslide Events in the United States

Abstract/Contents

Abstract
This polygon shapefile contains information on costly regional landslide events in the 50 United States and Puerto Rico. The extents of the regional events were drawn from the published literature and represent the approximate boundaries of extensive landsliding triggered by a single meteorological or seismic event. The regional extents should be considered approximate. In several cases the limits shown represent an arbitrary administrative boundary rather than the extent of landsliding related to a storm or earthquake. Costly events are defined as those where there was public or private property damage or loss of human life. Landslides are defined in a broad manner, to include most types of gravitational mass movement such as rockfalls, debris flows, and the failure of engineered soil materials. Landslide causes include earthquakes, reservoir draw-downs, and heavy precipitation. This is an updated version of the April 2001 map layer. This layer is part of the 1997-2014 edition of the National Atlas of the United States.
Purpose
These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the National Atlas of the United States in the use of these data.

Bibliographic information

Supplemental information The purpose of this project was to identify and compile data relating to the most costly landslide events in the United States. Damage estimates are generally direct costs, or calculable expenses incurred by owners of private or public property that were impacted by a landslide. Many of the highest costs were the result of damage to the transportation infrastructure. For example, the 1983 Thistle Landslide in Utah destroyed a section of both U.S. Highway 6 and the main line of the Denver and Rio Grande railway. Much of the estimated cost of $400 million was attributed to the damage to these transportation routes. Indirect costs such as those incurred through increased travel times, loss of jobs, and reduced income as a result of a landslide event can be significant. However, an accurate accounting of these costs is often difficult. For example, the April 1998 Anzar Road landslide in San Benito County, California severed a utility line that provided natural gas service to an adjacent county. Restaurants and other businesses were forced to close for a time, resulting in lost revenues, wages, and income for the people affected. An additional map layer showing costly individual landslide events is also available as part of the National Atlas of the United States. Individual events are those points where a single costly landslide occurred. Locations of these points were determined from published landslide maps and coordinates, and in several cases the points locate the nearest town or other geographic feature. In all cases the locations should be considered approximate. More information on the USGS National Landslides Hazards Program is available at <http://landslides.usgs.gov/.>
