Detailed Description
This satellite image shows Montagu Island, in the remote South Sandwich Islands, erupting in September 2005. A vent in the center of the island is erupting ash, which is drifting to the northeast, as well as a narrow lava flow (red) which has cut north through the island's ice cover to reach the ocean. The island is surrounded by sea ice.
