A NASA image shows Montagu Island's Mount Belinda in the South Sandwich Islands in eruption on September 23, 2005.  A reddish dot (center) marks a thermal anomaly over the active summit vent.  An ash plume rising above the summit cone casts a shadow on the glacier and is blown eastward by prevailing winds.  The reddish area extending to the north coast of the island is a lava flow that produces steam clouds where it enters the sea.  The eruption was first detected by satellite thermal alerts in October 2001.  Sea ice partially surrounds the island.
