    ByRishav Kothari

    New satellite measurements showing ground uplift around Mount Kupreanof have confirmed an ongoing magmatic intrusion beneath the volcano, adding a third line of evidence to months of elevated seismic activity and sulfur dioxide emissions. The Alaska Volcano Observatory (AVO) said the Aviation Color Code remains at Yellow and Volcano Alert Level at Advisory, with no indications from available data that an eruption is imminent.

    Seismic activity and sulfur dioxide emissions have increased at Kupreanof volcano in Alaska over recent months, likely due to magmatic intrusion beneath the volcano. Kupreanof is a heavily glaciated stratovolcano on the Alaska Peninsula with no known historical eruptions. Current data do not indicate an eruption is imminent.
