Landsat 8 Satellite Captures Heat from Persistent Lava Lake at Mount Michael Summit Crater
On August 24, 2026, the NASA-USGS Landsat 8 satellite acquired images showing volcanic activity at Mount Michael, a stratovolcano on Saunders Island in the remote South Atlantic. The Operational Land Imager captured natural-color and infrared imagery revealing heat from a persistent lava lake in the volcano's summit crater, accompanied by a visible volcanic plume and darkened snow on northern slopes, indicating ongoing activity. Mount Michael has hosted this lava lake and exhibited low-intensity volcanic activity for several years, as confirmed by thermal data from multiple satellites over the past 30 years. The volcanic activity and associated sulfur dioxide emissions continue to be monitored remotely due to the volcano's isolated location. (NASA "nasa-news-releases")
