Zavodovski Island is an uninhabited volcanic island in the Traversay Islands subgroup of the South Sandwich Islands. It lies 350 kilometres (217 mi) southeast of South Georgia Island. It is the northernmost of the South Sandwich Islands and the nearest to South Georgia.

The island is home to around a million pairs of breeding chinstrap penguins, which is the largest besides Antarctica.

History

Zavodovski Island was discovered and named by Russian Antarctic explorer Fabian Gottlieb von Bellingshausen on Christmas Eve, 1819. Bellingshausen named it after Lieutenant Ivan Zavodovski, who was captain of his ship, the Imperial Russian Navy sloop-of-war Vostok.[1]

A volcanic eruption was identified on the island on 2 May 2012, though the size of the eruption is unknown.[2] The volcano on the island erupted again in March 2016; by July, between one third and one half of the island was covered in ash, putting the penguin colonies at risk.[3]

Geography

The island is largely unglaciated. It is approximately 5 kilometres (3.1 miles) across with a peak elevation of 551 metres (1,808 feet) above sea level. The southernmost point is Fume Point, northeast of which rises Noxious Bluff and the southwestern headland is Pacific Point. The easternmost cape is Pungent Point, the northernmost Reek Point, the northwesternmost Acrid Point and the westernmost Stench Point.[4]

Mount Asphyxia, a stratovolcano also known as Mount Curry,[5][6] dominates the western side of the island while the eastern half is a low-lying lava plain. It is an active volcano, with fresh lava reported in 1830 and numerous indications of activity since. Approximately 50% of the island is composed of tephra.[2]

  • The island was the inspiration for the track '(Something's going down on) Zavodovski Island' by London jazz ensemble Portico Quartet.
  • The penguin colony was featured in the "Frozen Seas" episode of the 2001 BBC nature documentary series The Blue Planet.
  • The penguin colony was also featured in the "Islands" episode of the 2016 BBC nature documentary series Planet Earth II.[7]
