Scientists say Alaska's Cleveland Volcano is undergoing a continuous low-level eruption.
The activity began with an explosion early Saturday morning, followed by two other explosions hours later.
The Alaska Volcano Observatory and U.S. Geological Survey say satellites and cameras suggest low-level emissions of gas, steam and a small amount of ash. Satellites detected highly elevated surface temperatures at the summit.
The Federal Aviation Administration said there are no flight restrictions as a result.
The volcano in the Aleutian Islands is 940 miles southwest of Anchorage. Its most recent significant eruption began in February 2001 and featured three explosive events that sent ash clouds as high 39,000 feet above sea level. It also produced a rubbly lava flow and hot avalanche that reached the sea.

Scientists say there was a minor explosion at Alaska's Cleveland Volcano on Saturday morning.
The volcano in the Aleutian Islands is 940 miles southwest of Anchorage. The Alaska Volcano Observatory and U.S. Geological Survey say no eruption cloud has been detected, and the Federal Aviation Administration said there are no flight restrictions as a result.
The volcano's most recent significant eruption began in February 2001 and featured three explosive events that sent ash clouds as high 39,000 feet above sea level. It also produced a rubbly lava flow and hot avalanche that reached the sea.
The most recent minor ash emissions were observed in November 2012.
