Today, we share an animated gif of the lava dome growing at Great Sitkin volcano in the Aleutian Islands, seen in a series of high-res satellite radar (SAR) images July 25-Aug 27, 2021. The dome grew from ~90 m to ~1000 m across and is continuing to grow. Great Sitkin is currently at Color Code ORANGE and Alert Level WATCH.

A giant volcano in Alaska is showing signs of an impending eruption. Significantly elevated levels of volcanic gas emissions were recently observed around Mount Spurr, which is located 75 miles from Anchorage that is home to nearly 300,000 people. The Alaska Volcano Observatory said the emissions 'confirm' that new magma is flowing beneath the volcano, indicating an foreseeable eruption. 📷 US Geological Survey / Alaska Volcano Observatory / Google Maps #volcano #alaska #nature #news | America N

🚨 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

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

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.

Volcano Experts Say Alaska’s Mount Spurr is About to Erupt

AVO Information Statement Tuesday, July 29, 2025, 1:44 PM AKDT #Spurr (VNUM #313040) Current Volcano Alert Level: ADVISORY Current Aviation Color Code: YELLOW Summary • Monitoring data show that the shallow magma intrusion beneath Mount Spurr has stalled, but that magma deeper below the volcano may still be active. • The likelihood of an eruption is low but remains above background levels. We expect increases in seismic activity, gas emissions, surface deformation, and surface heating prior to a

Earthquakes, ground deformation, and melting of ice in the summit crater of Mount Spurr are some of the observations that have resulted in the volcano’s current elevated alert status. This animation shows the earthquakes detected by AVO in the proximity of Spurr volcano from December 1, 2024, to February 11, 2025. The earthquakes are presented in (a) a top-down view, (b) a N-S transect, and (c) a E-W transect cutting across Mount Spurr summit. Each earthquake, sized by their magnitude, first app
