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.
