The eruption of a volcano on Alaska’s Great Sitkin Island has sparked a red alert.
Authorities have issued a warning that a volcanic eruption from Alaska’s Great Sitkin volcano is either imminent or already underway.
The Alaska Volcano Observatory (AVO) has released a red aviation alert for Great Sitkin, indicating that “significant volcanic ash emission into the atmosphere is likely.”
At about 6 a.m. UTC (2 a.m. EDT) Wednesday morning, the observatory released a notice for aircraft warning that a “explosive eruption” had begun around an hour before, sending a cloud of ash high into the air.
According to early estimates, the eruption’s cloud had risen to a height of 15,000 feet and was still rising.
The cloud has separated from the volcano and is heading eastward after the eruption.
Additional fires, according to AVO, are probable. The Volcano Alert Level remains at “Warning,” and the Aviation Color Code warning remains red.
Great Sitkin is a volcano that dominates the northern half of Great Sitkin Island, which is part of the central Aleutian Islands, which extend westward from Alaska to Russia.
The volcano is located about 26 miles east of the Adak community.
