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.

A magnitude 5.6 earthquake struck about 58 miles southwest of Unalaska Sunday afternoon. While many locals felt the event, including in Nikolski and Akutan, there is no current threat of a tsunami or cause for concern.

The Great Sitkin volcano, located on a remote island 23 miles northeast of Adak, has been erupting since July 2021. Scientists have now discovered the reason behind the years-long eruption, which is helping them assess the volcano's potential hazards more accurately.

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.

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.

A group of scientists from Colorado is using drone technology to keep an eye on activity in Makushin Volcano.

Mount Shishaldin is simmering down after a Friday eruption sent an ash cloud across the eastern Aleutians, prompting the Alaska Volcano Observatory to raise the aviation color code to red.
