Bogoslof volcano erupts again; forces aviation alert

An Alaska volcano that has been active for nearly six months has erupted again.
The Alaska Volcano Observatory says Bogoslof Volcano in the Aleutian Islands erupted at 2:16 p.m. Sunday and sent a cloud of ash at least 35,000 feet high. The eruption lasted 55 minutes.
Ash can harm and stop jet engines. Ash from southwest Alaska volcanos is a threat for airliners operating between North America and Asia when a cloud rises above 20,000 feet.
