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.

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.

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
