The Alaska Volcano Observatory (AVO) reported that a small eruption producing minor ash emissions occurred from the summit crater starting around 05:13 local time yesterday.

Plume of ash rose to low altitude of 10,000 ft (3,000 m) and drifted S-SE as satellite imagery identified.
Fresh ash deposits are visible at the volcano's summit generated by the explosion.
Small ash content continued at the summit vent at 10:48 local time until visibility of the eruptive phase was limited due to dense clouds.
In addition, AVO recorded elevated surface temperatures detected in satellite data including continuous sulfur dioxide (SO2) emissions.
The alert level for the volcano was raised to "orange".

The Alaska Volcano Observatory (AVO) reported that the seismic tremor detected in June at the volcano has continued intermittently, but with decreasing frequency, and there have been no indications of surface change including increased temperatures or gas emissions. Tremor at the volcano in the past has sometimes preceded eruptions, but also can occur and persist for weeks to months and not result in an eruption. Current observations suggest activity has returned to near background, and thus the Aviation Color Code and the Volcano Alert Level are being decreased to Green/Normal. read all
