There are 169 potentially active volcanoes in the U.S. The mission of the USGS Volcano Hazards Program is to enhance public safety and minimize social and economic disruption from volcanic unrest and eruption. We accomplish this by delivering effective forecasts, warnings, and information about volcano hazards based on scientific understanding of volcanic processes.
