"In collaboration with state geological surveys and other federal agencies, USGS has compiled much of the existing landslide data into a searchable, web-based interactive map called the U.S. Landslide Inventory Map.

​

Where data are available, the searchable map provides links to original digital geospatial files for further information. The current landslide inventory is not comprehensive as further mapping is needed in many parts of the country. For example, absence or sparseness of mapped landslides in areas of steep topography points to locations where the knowledge of landslide history and activity is likely poor. Periodic updates of the database are planned as new or improved data become available, increasing the usefulness of the product."
