Landsat Satellite Images Confirm Persistent Lava Lake at Mount Michael Summit Crater
On August 24, 2026, the Operational Land Imager on NASA's Landsat 8 satellite captured images of Mount Michael, a volcano on Saunders Island in the South Sandwich Islands, revealing thermal anomalies indicative of a persistent lava lake within its summit crater. Additional satellite data from Landsat, Sentinel, and ASTER over 30 years support the presence of this lava lake. Ongoing low-intensity volcanic activity and sulfur dioxide emissions have been detected by instruments such as MODIS, VIIRS, and NASA's Aura satellite. These observations rely on satellite monitoring due to the remoteness of the location.
