Scientists have downgraded the threat level of Alaska's Pavlof Volcano.

The Alaska Volcano Observatory says it lowered the advisory level for Pavlof on Tuesday from orange to yellow, which means activity has decreased significantly but continues to be closely monitored.

The volcano 625 miles southwest of Anchorage began erupting May 13.

Scientists reported plumes of steam, gas and ash reached up to 22,000 feet and were visible on satellite images and from nearby communities. Seismic activity was elevated.

The observatory says the 8,262-foot volcano has calmed over the past three days but adds that the pause doesn't necessarily mean the eruption has ended.

Cleveland Volcano, 940 miles southwest of Anchorage, remains at orange, with slightly elevated surface temperatures indicating a cooling lava flow.
