The Cleveland volcano in the east central Aleutians is showing signs of heating up. The Alaska Volcano Observatory reports that increased surface temperatures and ash indicate the volcano has entered a period of unrest. According to the release, the alert level for Cleveland was bumped up to advisory, meaning the possibility of explosions has increased.

The Cleveland volcano is located on the uninhabited Chuginadak Island about 45 miles west of the community of Nikolski. Its last major eruption was in 2001 and it has been active intermittently since then.
