The 5-km-wide Zavodovski Island, the northernmost of the South Sandwich Islands, consists of a single 551-m-high basaltic stratovolcano with two parasitic cones on the east side. Mount Curry, the island's summit, lies west of the center of the island, which is more eroded on that side. Two fissures extend NE from the summit towards the east-flank craters, and a lava platform is located along the eastern coast. Zavodovski is the most frequently visited of the South Sandwich Islands. It was erupting when first seen in 1819 by the explorer Bellingshausen, and the volcano has been reported to be smoking during subsequent visits.

|Steam clouds rise from glacier-clad Mount Curry, the 551-m-high summit of Zavodovski Island in this aerial view from the south. Icebergs lie off the shores of the 5-km-wide island, the most frequently visited and northernmost of the South Sandwich Islands. Two young eruptive fissures extend NE from the summit toward craters located below the icecap on the east flank and were the source of a lava platform extending toward Pungent Point (right).
