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).

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.

Two ash eruptions from Shishaldin Volcano disrupted air travel to the Aleutians Tuesday.

Shishaldin volcano, which has been erupting for days, sent an ash cloud 40,000 feet into the air above Unimak Island early Friday morning.

A volcano on Unimak Island in the Eastern Aleutians is on watch for an eruption — Shishaldin is spewing lava at its summit, but the real threat is if it starts to emit ash.

Earthquake activity has decreased at two western Aleutian volcanoes, reducing the potential for an eruption.Thursday, the Alaska Volcano Observatory lowered the alert levels for remote Tanaga and Takawangha Volcanoes, about 60 miles west of Adak.
