The Alaska Volcano Observatory says a brief eruption at Cleveland Volcano in Alaska’s Aleutian Islands sent up an ash cloud that quickly dissipated.
Geophysicist Dave Schneider says the cloud rose as high as 15,000 feet and dissipated in about two minutes. He says the cloud was not a hazard to aviation.
Schneider says the explosion at 4:38 a.m. Thursday was similar to small events at Cleveland Volcano since December. Those explosions created ash clouds that dissipated quickly and did not affect air traffic.
Cleveland Volcano is a 5,675-foot peak on an uninhabited island 940 miles southwest of Anchorage.
Scientists detected the explosion based on seismic information recorded at stations at nearby volcanoes.
