The Alaska Volcano Observatory reports a rare and concerning natural event unfolding in the Aleutian Islands, where three volcanoes are actively erupting, and a fourth is showing signs of potential activity.
The AVO has labeled the Great Sitkin, Pavlof, and Semisopochnoi volcanoes as “restless,” noting ash and steam emissions. These volcanoes are classified as an “orange” threat level, indicating active eruptions. Meanwhile, Cleveland volcano remains at a “yellow” level, signaling unrest but no eruption yet.
Using surveillance cameras and eyewitness reports, the AVO tracks the volcanic activity. Pavlof, a snow-capped stratovolcano, is currently the most active, with minor explosions and ash plumes extending up to six miles. Located 35 miles from Cold Bay, it poses no immediate danger to the nearby community.
Great Sitkin's lava activity is ongoing, situated close to two small communities. On Semisopochnoi, the volcano is ejecting ash plumes reaching heights of up to 10,000 feet.
Seismic movements have been observed at Cleveland volcano, which experienced an eruption last year. Additionally, minor earthquakes have been noted at the Atka Volcanic Complex.
AVO geologists remain cautiously observant. Although multiple volcanoes are active, the current eruptions are not considered life-threatening. However, they warn that Pavlof has a history of escalating its eruptions abruptly.
Alaska holds the notable distinction of witnessing the 20th century's most impactful volcanic eruption, Novarupta, in 1912. The three-day event spread ash over hundreds of miles, forming the Katmai Caldera and the Valley of Ten Thousand Smokes.
