Monitoring Trends in Burn Severity: Fire Occurrence Locations and Burned Area Boundaries in the US

This map shows the Fire Occurrence Locations and Burned Area Boundaries from the beginning of the Landsat Thematic Mapper archive to the present in the US. The Monitoring Trends in Burn Severity (MTBS) project maps the location, extent, and severity of all large fires in the conterminous United States, Alaska, Hawaii and Puerto Rico from the beginning of the Landsat Thematic Mapper archive to the present. All documented fires greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. The data was updated on 03-31-2020.
