There have been no eruptions since Dec. 25 and Dec. 29, which destroyed the earlier lava dome built up over the fall.

Cleveland is a 5,675-foot peak on an uninhabited island 940 miles southwest of Anchorage.

Authorities say sudden eruptions could occur at any time, and ash clouds 20,000 feet above sea level are possible.
