Alert raised around Alaska volcano after likely 'single explosion'
A heightened state of alert has been issued for a remote Alaskan volcano after the detection of a drifting ash cloud, the result of what's believed to have been a lone explosion.
The U.S. Geological Survey put out an orange alert Thursday for Cleveland Volcano in the Aleutian Islands, about 940 miles southwest of Anchorage. That is third out of four possible levels on the federal agency's warning scale.
"Satellite data indicate that this is a single explosion event," the survey and Alaska Volcano Observatory said in its notice, but "more sudden explosions producing ash could occur with plumes exceeding 20,000 feet above sea level,"
A similar alert had been issued in early September, amid concerns that the volcano could be leaking from its flanks if the lava inside continued to build up. The volcano's lava dome was 262 feet in diameter on August 30, but by then in had expanded to 394 feet.

(36,988 posts)One of the most active volcanoes in the Aleutian Arc, Cleveland has erupted at least 21 times in the last 230 years. A VEI 3 eruption in 1944 produced the arc's only direct volcanic fatality.
Most recently Mount Cleveland has erupted three times in 2009, twice in 2010, and once in 2011.[1] The volcano's remoteness limits opportunities for its study, and the Alaska Volcano Observatory relies heavily on satellites for monitoring.
The volcano is primarily hazardous to aircraft; many of the flights over the north Pacific approach the vicinity of the volcano, and volcanic ash released from eruptions can damage sensitive electronic equipment and sensors.
