Highest nearest volcano by state

Miles to nearest potentially active volcano.

This measure has no better end. The order describes the states, it does not rank them — see the other direction.

Straight-line miles from the county’s population-weighted center to the nearest of the 161 potentially active U.S. volcanoes in the USGS Volcano Hazards Program inventory. The map marks the inventory locations. “Potentially active” is the USGS inventory category, not a prediction of eruption or a hazard-zone boundary; actual exposure depends on volcano type, terrain, prevailing winds and emergency planning.
