The United States has the third-highest number of active volcanoes in the world, after Indonesia and Japan. It’s home to the largest active volcano on Earth, as well as a supervolcano that could blanket the Midwest in ash.
The high number of volcanoes is down to the U.S.’s geology, with many sitting along the Pacific Rim in the “Ring of Fire” — a 25,000 mile (40,000 kilometers) chain of volcanic and seismically active sites where the Pacific plate and other tectonic plates meet. The vast majority are located in the Aleutian Islands, the Alaska Peninsula, the Hawaiian Islands and the Cascade Range of the Pacific Northwest.
There are 160 named volcanoes in the United States and its territories that potentially pose a threat, according to a 2018 assessment by the U.S. Geological Survey. These include 18 considered to be a “very high threat,” 39 “high threat,” 49 of “moderate threat,” along with 34 “low threat” and 21 “very low threat.”
