Which Antarctic archipelago includes King George Island and Deception Island?

The Antarctic archipelago that includes King George Island and Deception Island is the South Shetland Islands.

The chain lies north of the Antarctic Peninsula and stretches across the Southern Ocean. King George Island is its largest island and hosts numerous scientific research stations, making the group one of the most frequently visited parts of Antarctica.

Deception Island is especially distinctive because much of its centre is flooded by the sea. Its horseshoe-shaped harbour formed after a volcanic collapse, and the island remains volcanically active. Livingston Island, Elephant Island, and Smith Island are also part of the South Shetland group.

The name is easy to confuse with the South Orkney Islands, another Antarctic island group farther east. The Palmer Archipelago, by contrast, lies closer to the Antarctic Peninsula, while the Balleny Islands are much farther south in the Ross Sea sector.
