The U.S. Geological Survey conducts post-fire debris-flow hazard assessments for many major fires across the Western United States. The information from these assessments is provided in an interactive map, allowing users to view fires by location or name and access detailed maps of debris-flow probability in the area affected by each fire. Users can select fires by year back to 2013.

"LIDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.
