Documenting landslides in Puerto Rico caused by Hurricane Maria.

Bill Schulz, USGS Research Geologist, takes photographs of Puerto Rican hillsides from a U.S. Army helicopter to document landslides caused by Hurricane Maria. This work will help identify areas around Puerto Rico with the highest risk of more landslides, which is information the Federal Emergency Management Agency will use to determine the best way to mitigate and prepare for any future landslides.
