FAQ
USA has 25 catalogued volcanoes in the Smithsonian Global Volcanism Program dataset, 24 currently classified as active, and 10 have erupted since 2000. About 0.9 million people live within 30 km of one.
Our eruption-forecast model rates Mauna Loa the most likely to erupt in the next 12 months in USA, at roughly 32.5% (about one eruption every 3 years on average). This is a statistical estimate, not a prediction — follow official volcano-observatory advisories.
By population exposure — the number of people within 30 km weighted by eruption probability — the most dangerous volcano in USA is Mauna Loa, with about 80,000 people within 30 km and a modeled 32.5% one-year eruption probability.
The most recent eruption in our dataset for USA was at Kilauea in 2024.
