🚨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

🚨 SHISHALDIN VOLCANO ALERT RAISED – AUGUST 25, 2025 🚨 The Alaska Volcano Observatory has raised Shishaldin’s alert level to ADVISORY (YELLOW) after a surge in seismic tremors, infrasound, and sulfur dioxide gas. Steaming from the summit has intensified. These are the same signals recorded before the 2023 eruption that disrupted international flights. Shishaldin erupts with little warning. Flight paths and communities near Unimak Island are now on alert. #Shishaldin #AlaskaVolcano #VolcanoAlert
