Great Sitkin Volcano: Slow Eruption Continues
US · Published Sep 22, 2026
• The Great Sitkin Volcano in Alaska continues its slow eruption, which began in July
• Lava flows have filled much of the summit crater and extended into nearby valleys. No explosions have been recorded since May 2021, and recent monitoring indicates no significant earthquake activity. However, satellite and webcam observations have been limited due to cloud cover. The volcano remains under a 'WATCH' alert level and an 'ORANGE' aviation color code, signaling ongoing activity that could affect air travel.

Impact & Risks

The ongoing eruption poses localized risks, particularly to aviation, due to potential ash emissions. While no explosions have occurred recently, the slow lava flow could impact nearby ecosystems and infrastructure if activity intensifies. The volcano is closely monitored to mitigate risks to residents and air traffic in the region.
