🚨Alaska’s Ring of Fire is active The Alaska Volcano Observatory currently has three volcanoes on alert at the same time, all sitting on the Aleutian arc. First, Great Sitkin Volcano. Lava has been slowly erupting inside its summit crater since 2021, filling most of the crater with a thick flow. As of January 17, 2026, AVO lists Great Sitkin at WATCH with an ORANGE aviation color code. That means the eruption is still ongoing and ash is possible if activity changes, even though seismicity is low

🚨ALASKA RING OF FIRE: VOLCANO ALERTS AND EARTHQUAKES TOGETHER In the last 48 hours, the Alaska Volcano Observatory has kept Great Sitkin Volcano at WATCH / ORANGE, confirming that lava is still actively erupting inside the summit crater. This eruption has been going on since 2021, slowly filling the crater with new lava. Small local earthquakes continue to be recorded near the volcano, a sign that magma is still moving and the system is not done yet. Shishaldin Volcano is currently at ADVISORY

3 years of lava effusion at #GreatSitkin! After a brief explosive eruption on May 25, 2021, lava began oozing out of a vent in the summit crater in July 2021. The first sign of new lava at the surface was a July 23, 2021 satellite radar Terra-SAR-X image. These radar images can see through the persistent clouds of the Aleutian Islands and show an incredible time series animation of the lava flow growth. The most recent lava flows have oozed out above the vent and overtopped early emplaced lavas.
