'Mount Cleveland' is an active stratovolcano that forms the western half of Chuginadak Island in the central Aleutian Islands of Alaska. The Alaska Volcano Observatory currently lists Cleveland as Aviation Color Code ORANGE and Volcanic-Alert Level Advisory, meaning a small ash eruption is expected or underway, with the ash plume(s) not expected to rise above 25,000ft above sea level. This symmetrical volcano is one of the most active of the volcanoes in the Aleutians and has been the site of numerous eruptions in the last two centuries; the most recent eruption occurred in 2005, although it has spewed numerous clouds of ash since then, most recently on August 24, 2006. In 1944, a U.S. Army serviceman was reportedly killed by an eruption from Mount Cleveland, the only known eruption-related fatality in the Aleutian Islands.
At an elevation of 1,730 m (5,676 ft.), this volcano is the highest in the Islands of Four Mountains group. Carlisle Island to the north-northwest, another stratovolcano, is also part of this group. Magma that feeds eruptions of ash and lava from Mount Cleveland is generated by the northwestward movement of the Pacific Plate beneath the North American Plate.
