Which South Atlantic archipelago contains Zavodovski, Candlemas, and Saunders islands?

The South Atlantic archipelago containing Zavodovski, Candlemas, and Saunders islands is the South Sandwich Islands.

The islands form a remote, volcanic island arc southeast of South Georgia. They were created where the South American Plate is forced beneath the Scotia Plate, producing steep stratovolcanoes and submarine volcanoes. The chain is politically part of the United Kingdom’s South Georgia and the South Sandwich Islands overseas territory, although Argentina also claims sovereignty.

Zavodovski is the northernmost island and is famous for its immense chinstrap penguin colony and sulfurous volcanic activity. Candlemas belongs to the northern Candlemas Islands group, while Saunders lies among the central islands. Mount Michael on Saunders has a persistent lava lake, one of the world’s rarest volcanic features.

The South Sandwich Islands are uninhabited. Their remoteness and harsh seas distinguish them from the Falkland Islands and Tristan da Cunha, while the South Orkney Islands belong to a separate Antarctic archipelago.
