Mount Belinda is a stratovolcano on Montagu Island, in the South Sandwich Islands of the Scotia Sea. At 1,370 m (4,490 ft), Mount Belinda is the highest peak in the South Sandwich Islands, a part of South Georgia and the South Sandwich Islands.[3]
Belinda was inactive until late 2001, when it erupted, the eruption lasting until 2007.[4] The eruption produced large quantities of basaltic lava, melting the thick cover of ice that had accumulated while the volcano lay dormant, and "producing a marvelous 'natural laboratory' for studying lava-ice interactions relevant to the biology of extreme environments, as well as to processes believed to be important on Mars."[2]
The activity throughout 2005 marked the highest levels yet. The increase in activity in the fall of 2005 produced an active 3.5-kilometre-long (2.2-mile) lava flow, extending from the summit cone of Mount Belinda to the sea. The flow spread northeast from the volcanic vent, and then became diverted due north by an arête.[1] By late 2007, eruptive activity had ceased,[1] and in 2010 the only activity was from scattered fumaroles and cooling lava.
