A January 13, 2006 view of the north side of Montagu Island shows the lava field formed by a recent eruption and a plume rising above Mount Belinda.  Montagu is the largest of the South Sandwich Islands and consists of a massive shield volcano cut by a 6-km-wide, ice-filled summit caldera.  There was no record of Holocene or historical eruptive activity at Montagu until satellite data, beginning in late 2001, revealed thermal anomalies consistent with lava lake activity.
