Landsat satellite images show persistent lava lake in Mount Michael summit crater
On August 24, 2026, NASA’s Landsat 8 satellite captured images of Mount Michael, a stratovolcano on Saunders Island in the South Sandwich Islands, revealing heat signatures from a persistent lava lake in its summit crater. This lava lake activity has been ongoing for several years, as indicated by thermal anomaly data from multiple satellite instruments including Landsat, Sentinel, ASTER, MODIS, and VIIRS. Volcanic plumes and sulfur dioxide emissions have also been observed, confirming continuous volcanic activity. Saunders Island is located in a remote region where satellite observations are essential for monitoring volcanic activity.
