    ByTeo Blašković

    Alaska’s Trident volcano has seen a significant increase in seismic activity and ground uplift over the past five months, leading to concerns about a potential volcanic eruption. The Alaska Volcano Observatory (AVO) has confirmed that this unrest is the result of magma intrusion beneath the volcano. The rising magma, which can trigger an eruption, has also caused increased seismic activity in the neighboring volcanoes of the Katmai volcanic cluster, including Katmai, Martin, Mageik, and the Novarupta vent.
