Mount Cleveland– Alaska

Mount Cleveland (also known as Cleveland Volcano) is a nearly symmetrical stratovolcano on the western end of Chuginadak Island, part of the Islands of Four Mountains about west of Umnak Island in Alaska's Fox Islands. Mt. Cleveland stands at 5,675 feet (1,730 meters) and is one of the most active of the Aleutian Arc's 75 volcanoes. The island was called after Chuginadak, the Aleutian fire goddess, who they thought inhabited the volcano. Mount Cleveland was named after then-President Grover Cleveland by a team from the United States Coast and Geodetic Survey that visited the island in 1894.

Cleveland, one of the Aleutian Arc's most active volcanoes, has erupted at least 22 times in the last 230 years. The arc's lone documented volcanic fatality occurred in 1944, when a VEI 3 eruption occurred. Mount Cleveland erupted three times in 2009, twice in 2010, once in 2011, and once each in 2016, 2017 and 2018. The volcano's remoteness limits opportunities for its study, and the Alaska Volcano Observatory relies heavily on satellites for monitoring. The volcano is mostly dangerous to planes since numerous flights across the north Pacific go close to it, and volcanic ash created by eruptions can harm sensitive electronic equipment and sensors.
