The alert level for a remote Alaska volcano has been lowered for lack of activity in the past 10 days.

The Alaska Volcano Observatory on Friday reduced the alert status for the Cleveland Volcano.

The center in a release says there have been no explosions detected since March 13, and there's no evidence the lava dome has grown in that time.

The center says there are no significant deposits of ash on the volcano, suggesting earlier eruptions might have been relatively ash-poor.

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

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