On September 20, 2017, Hurricane Maria hit the U.S. territory of Puerto Rico as a category 4 storm. Heavy rainfall caused landslides in mountainous regions throughout the territory. This data release presents geospatial data describing the concentration of landslides generated by Hurricane Maria in Puerto Rico. We used post-hurricane satellite and aerial imagery collected between September 26, 2017 and October 8, 2017 to visually estimate the concentration of landslides over nearly the whole territory. This was done by dividing the territory into a grid with 4 square km cells (2 km x 2 km). Each 4 square km grid cell was classified as either containing no landslides, fewer than 25 landslides/ square km or more than 25 landslides/ square [...]

The purpose of this study was to evaluate the distribution of landslides caused by Hurricane Maria in Puerto Rico and to support response and recovery efforts. We used three categories to describe landslide concentration: severely impacted by landslides (greater than 25 landslides/square km), moderately impacted by landslides (less than 25 landslides/ square km), and not impacted by landslides. GIS map data include a 2 km x 2 km grid covering the entire extent of Puerto Rico in which the relative landslide concentration of each grid cell is identified.
