Volcanic Maps

The USGS Volcano Hazards Program enhances 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. Learn more by exploring USGS volcanic maps.
