Great Sitkin Volcano maintains Orange alert as lava flows continue in summit crater
The Alaska Volcano Observatory has kept Great Sitkin at an ORANGE WATCH level, noting that slow-moving lava continues to erupt within the volcano's summit crater.
Volcanologists with the Alaska Volcano Observatory are monitoring activity at Great Sitkin in the Aleutians region of Alaska. The observatory issued a status update on October 1, 2026, confirming that lava flows persist inside the summit crater.
The current eruptive phase began in July 2021 and has been ongoing since then. Lava flows have progressively filled portions of the volcanic interior during this period.
Seismic activity remains a component of the monitoring picture; minor earthquakes were detected over the past day, though no significant tectonic shifts or major tremors are reported.
Satellite imagery and webcam feeds intended to track the eruption's progress remain obscured by cloud cover. This atmospheric condition limits direct visual confirmation of flow extent.
The Alaska Volcano Observatory maintains an ORANGE alert for Great Sitkin, indicating that while the volcano is active and hazardous conditions exist near the summit area, there are no immediate threats requiring evacuation or emergency orders.
While lava continues to move slowly within the crater, specific dimensions of filled areas remain incomplete in current records. The observatory's primary focus remains tracking flow direction and potential changes in eruptive intensity as weather permits clearer observation.
Residents near Great Sitkin should continue following official advisories for safety regarding volcanic hazards.
