A remote volcano in Alaska’s Aleutian Islands erupted violently early yesterday, throwing up an ash cloud 4,570 metres into the sky.
The Cleveland Volcano, located on an uninhabited island 1,500 kilometres southwest of Anchorage, has been active since July.
Located directly below commercial flight paths between Asia and North America, scientists said further explosions producing larger ash clouds are possible and could come without warning, the observatory said.
“Satellite data indicate that this is a single explosion event, however, more sudden explosions producing ash could occur with plumes exceeding 20,000 feet above sea level. Such explosions and their associated ash clouds may go undetected in satellite imagery for hours.
“However, in cooperation with the University of Washington, AVO has implemented a lightning alarm system that may detect significant ash-producing events within minutes of onset,” said the AVO.
