Cleveland Volcano, known to the Alaska Volcano Observatory as Cleveland,[5] and often known as Mount Cleveland, is an active stratovolcano that forms the western half of Chuginadak Island in the central Aleutian Islands of Alaska. Chuginadak is the native Aleut language name for the volcano, named after the traditional Aleut goddess of fire.[6] Its current name was the name it was given on page 75 of the 1944 Aleutian Coast Pilot.[7] Cleveland, a symmetrical volcano, is one of the most active of the volcanoes in the Aleutian Islands[2] and has been the site of numerous eruptions in the last two centuries; the most recent eruptive event was a brief, explosive ash emission on January 2, 2009, that reached a height of 20,000 feet (6 km) before drifting east-southeast about 150 miles (241 km) and dispersing over the North Pacific Ocean.[8] 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.[9]  At an elevation of 5,676 feet (1,730 m), Cleveland is the highest volcano 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 Cleveland is generated by the northwestward movement of the Pacific Plate beneath the North American Plate.[10] 
[edit] 1944 eruptionFrom June 10-13, 1944, Cleveland experienced a Vulcanian eruption from a vent in its central crater,with a maximum VEI of 3, sending ash 6,000 meters (19,685 ft) into the air. Chuginadak Island was evacuated, but one soldier, a member of the Eleventh Army Air Force Division on a reconnaissance mission, advanced too close to the erupting vent and was killed, possibly by a mudslide. His death was the only known fatality ever to result directly from an Alaskan volcanic eruption.The evacuation of Chuginadak Island remained in effect until the end of World War II.[11] [edit] 2006 eruptionFrom August 24-October 28, 2006, Cleveland erupted intermittently and explosively with a maximum combined VEI of 3. The eruption on August 24 prompted the Alaska Volcano Observatory to raise the Level of Concern Color Code to YELLOW (Advisory). Then, on October 28, the Level of Concern Code was raised to ORANGE (Watch) for two hours after a jetliner pilot saw a plume rising from the volcano to 30,000 feet (9,144 m) in altitude, but estimates taken from satellites found the plume to be much lower, and the Level of Concern Code was again brought back down to YELLOW.[12]  [edit] 2009 eruptionBeginning approximately October 5, 2009, Cleveland is erupting again. The ash plume is about 20,000 feet high. Developing story, citation is here: http://www.ktuu.com/Global/story.asp?S=11253458 [edit] See also[edit] References
