The 5-km-wide Zavodovski Island, the northernmost of the South Sandwich Islands, consists of a single basaltic stratovolcano with two 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 E-flank craters, and a lava platform is located along the eastern coast. The volcano was producing abundant emissions when observed in 1819 by the explorer Bellingshausen. A landing party in 1830 also reported strong emissions along with a fresh lava field on the east side from which pumice was being eroded into the ocean.
