Mount Belinda is a stratovolcano on Montagu Island, in the South Sandwich Islands of the Scotia Sea.

[3] 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 (2.2-mile)-long 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.
