The Alaska Volcano Observatory says the downgrading Thursday from "watch" to "advisory" comes after satellite images of the volcano over the past three weeks indicated no significant growth of the lava dome.
In early October, lava had reached the edge of the crater of the 5,675-foot volcano, located on Chuginadak Island, about 940 miles southwest of Anchorage.
The observatory says activity at Cleveland could resume, indicating lava could overflow the rim. The mountain also could erupt and send up an ash cloud that could threaten aircraft.
The nearest village, Nikolski, is on another island about 50 miles east and has 18 permanent residents. The village was not considered at risk in previous eruptions of the volcano.
