🚨 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

🚨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

⚠️🌍 BREAKING: Great Sitkin Volcano Erupts in Alaska’s Aleutian Islands 🌍⚠️ Great Sitkin, one of Alaska’s most active volcanoes, is showing powerful new activity: 🔥 Lava fills the summit crater — steady growth of lava flows now pushing down the southwest slope. ⛰️ Rockfalls triggered as unstable slopes collapse under the pressure of molten rock. 🚨 Hazards: Lava may enter valleys below, endangering terrain, ecosystems, and potential infrastructure. ✈️ Air traffic risk: Elevated heat, steaming,

Watch: Steam emits from summit peak of Alaska's Mount Spurr amid increased unrest

Continuing our anniversary posts marking 3 years of lava extrusion at #GreatSitkin, here’s a video collected Sept 3, 2023 by M. Loewen, showing the lava-ice contact and panning over to the active vent area. Alaska Volcano Observatory geologists were able to visit and sample Great Sitkin volcano’s active lava flow in September 2023. Analyses of these lavas shows that the composition is a fairly typical basaltic andesite. usgsvolcanoes USGS Volcanoes uafgi UAF Geophysical Institute Alaska DGGS #al

Mount #Spurr update: On Dec 18, an AVO crew conducted a gas and observation flight of Mount #Spurr to measure volcanic gases (H2O, SO2, CO2, H2S) and do a photo survey of the summit region and Crater Peak. The new gas measurements showed no significant changes from the last gas flight at Spurr in June. The lake, which formed earlier this year, has greatly increased in size since June, and is mostly covered in snow and ice with some floating yellow sulfur. Enjoy this video taken during the flight
