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.

The eruption of lava at Great Sitkin in the Aleutians has now reached an impressive fourth birthday! The lava flow started sometime in late July 2021. Enjoy this compilation of radar satellite data, which shows the growth of the flow and dome since then. #Alaska #volcano USGS Volcanoes UAF Geophysical Institute Alaska DGGS Alt text: This video shows a series of stills of somewhat grainy, black-and-white views of Great Sitkin from a top-down view.

🚨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

Far from the Alaskan mainland is a secluded island in the Bering Strait. Here the views span for an eternity, Russia is within sight, and the Siberian Yupik People are living a unique lifestyle removed from everyone. Come join me to see what this unknown sliver of America looks like on the ground. ► Video edited by: Natalia Santenello ► Researched by: Kymberly Redmond All rights reserved © 2022 Peter Santenello #alaska #alaskalife | Peter Santenello

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
