ANCHORAGE, Alaska – An Alaska volcano that has been active for almost six months has again erupted.
The Alaska Volcano Observatory says Bogoslof (BOH-gohs-lawf) Volcano in the Aleutian Islands erupted at 2:16 a.m. Sunday and sent a cloud of ash at least 35,000 feet (10,668 meters) high. The eruption lasted 55 minutes.
Ash can harm and stop jet engines. Ash from the south-west of Alaska volcanoes, is a threat to the aircraft between North America and Asia as a cloud above 20,000 feet (6,096 meters).
After the eruption, the Aviation Color Code was raised to red, the highest level.
The agency says that a person at a nearby Unalaska Island, reports seeing a large white-grey mushroom cloud form on Bogoslof, with an axis to the west.
