The activity level of an Alaska volcano has declined after the mountain erupted with a massive ash cloud that prompted the cancellation of dozens of flights.
The U.S. Geological Survey said in a news release late Monday night that the intensity of the eruption had "declined significantly."
Pavlof Volcano, one of Alaska's most active volcanoes, is 625 miles southwest of Anchorage on the Alaska Peninsula, the finger of land that sticks out from mainland Alaska toward the Aleutian Islands.
The volcano in the 8,261-foot mountain erupted about 4 p.m. Sunday, spitting out an ash cloud that rose to 20,000 feet.
