A volcano on Atka Island in the Aleutians has been showing increasing signs of unrest over the past two weeks, and scientists say the uptick in activity is significant enough to warrant a closer watch.

Emergency officials in Unalaska are closely watching an active volcano near Anchorage. Scientists said Mount Spurr is likely to erupt within weeks or months.

The Alaska Volcano Observatory detected an explosion at Korovin Volcano at 7:26 p.m. Thursday, and moved the Aviation Color Code and Alert Level to “watch”. Officials later reduced the threat level to advisory status.

The National Weather Service has issued a special weather statement for the Eastern Aleutians and Alaska Peninsula. According to the organization, small amounts of ashfall are possible in Unalaska, Nikolski, Sand Point and Cold Bay through Monday afternoon.

A small volcanic eruption occurred on Atka Island Wednesday night. But it was short-lived and no significant ash emissions were observed in satellite images, according to the Alaska Volcano Observatory (AVO).

Alaskan scientists are using machine learning to help identify what ash deposits go with what volcano. They say it helps identify what threat-level volcanoes are today.

Ash clouds from two volcanoes have disrupted air travel in the Aleutians, including Unalaska, preventing some patients from reaching medical care in Anchorage.

Over 100 earthquakes were recorded at the Bogoslof volcano earlier this week, which is located 61 miles northwest of Unalaska.

Strong winds on the Alaska Peninsula Monday swept volcanic ash from a 1912 eruption across the region, triggering a SIGMET warning from the National Weather Service.

The National Weather Service has ended an aviation warning for the Aleutian Islands issued after a massive eruption at Russia’s Shiveluch Volcano this week produced an ash cloud that drifted over the region.
