Atka volcano (Aleutian Islands): Volcanic Alert Level raised to Yellow

The alert level for the volcano was raised to „yellow“, as an elevated seismic activity has been recorded.
The Alaska Volcano Observatory’s seismic network detected a series of small, shallow earthquakes yesterday. Earthquakes were located 7 km southwest of the Korovin volcano at depths between 3 and 6 km.
Earthquakes represent an increase from background seismic activity, but may not necessarily lead to an eruption.
