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.
A major eruption is ongoing at Shishaldin volcano in Alaska, with satellite imagery suggesting the top of the ash cloud was approaching 12 km (40 000 feet) above sea level just before 08:00 UTC on July 23, 2023. As a result, the Aviation Color Code was again raised to Red.
