Which U.S. state has the most active volcanoes?

Alaska is notable for having the most active volcanoes of any U.S. state, with over 130 recognized volcanic peaks. This is largely due to its position within the Pacific Ring of Fire, a region characterized by intense seismic activity and numerous volcanoes as a result of tectonic plate movements. The Aleutian Islands, which stretch off the southern coast of Alaska, contain many of these volcanoes, some of which are frequently monitored for activity.

While Hawaii is also well-known for its volcanic activity, particularly with the ongoing eruptions at Kilauea and Mauna Loa, it does not surpass Alaska in the total number of active volcanoes. Washington and Oregon also have significant volcanic activity, including iconic peaks like Mount St. Helens and Mount Hood, respectively, but again, they do not match Alaska’s extensive volcanic landscape. This geographical context underlines why Alaska holds the title for the most active volcanoes in the United States.
