Interactive map of coastal change hazards in the United States

The U.S. Geological Survey's Coastal Change Hazards Portal provides an interactive map showing the hazards posed to U.S. coasts from extreme storms, shoreline change, and sea-level rise. The map includes:

  • Probabilities of collision, overwash, and inundation from nor'easters (Atlantic coast) and hurricanes (Atlantic and Gulf coasts) of different intensities, with predicted water levels and shoreline erosion effects.
  • Beach morphologies on the Atlantic and Gulf Coasts
  • Historical shoreline positions for the entire coastal United States
  • Shoreline change forecasts due to long-term sea-level rise
  • Coastal vulnerability due to sea-level rise on Atlantic, Gulf, and Pacific coasts
  • Detailed coastal hazard forecasts and histories for selected current or recent hurricanes, tropical, and extratropical storms

Users can download datasets for further use and analysis.
