Isla Zavodovski

Zavodovski

Estratovolcán · United Kingdom · 551 m

Steam clouds rise from fumaroles near the summit of Mount Curry, on Zavodovski Island, in this aerial view from the south. Icebergs lie off the shores of the approximately 4.5-km-wide island, the northernmost of the South Sandwich Islands. The eastern coast (right) comprises lava flows and is low-lying, contrasting with the cliffs of the west (left). Two young eruptive fissures extend NE from the summit toward craters on the east flank and were the source of a lava platform extending toward Pungent Point (right).

Resumen geológico

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.
