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.

⚠️🌍 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,

Video showing six hours of seismic data leading up to the May 25, 2021 Great Sitkin eruption. The number of earthquakes steadily increases leading up to the eruption at 05:04 UTC (09:04 AKDT), when the earthquakes cease. The top panel shows the spectrogram, and below is the seismic data. The audio is the subaudible seismic signal mapped to the range of human hearing. Video created by David Fee and Liam Toney, UAFGI/AVO | Alaska Volcano Observatory

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.
