Alaska volcano restless again; scientists increase threat level

The observatory’s coordinating scientist, David Fee, says the 8,225-foot (2,500-meter) volcano became active Saturday. Fee says small and sparse ash emissions seen rising to the 10,000-foot (3,050-meter) level prompted the threat level change.

The volcano erupted for several months in 2013. Other recent eruptions occurred in 2005 and between 1993 and 1995.

Veniaminof is 480 miles (772 kilometres) southwest of Anchorage on the Alaska Peninsula.

Fee says Cleveland Volcano in the central Aleutian Islands is Alaska’s most active volcano, with the last explosion in May.
