Torishima seen from the sea |
Torishima ( Japanese 鳥島 , literally: Bird Island , formerly Ponafidin Island ) is a small island of volcanic origin in the Pacific Ocean . It is the second southernmost island in the Izu Islands . To distinguish it from other Japanese " bird islands ", it is sometimes referred to as Izu-Torishima .
administration
Like the entire chain of Izu Islands, Torishima belongs administratively to Tokyo Prefecture . They are part of the Hachijō sub-prefecture, which is administered from Hachijō-jima . However, like the three Izu Islands Bayonnaise Rocks , Sumisu-jima and Sōfugan, they do not belong to any municipality and are therefore de facto an area free of municipalities . However, they are claimed by the communities of Aogashima and Hachijō .
geography
Torishima is located about 575 km south of Tokyo and 76 km north of the rocky island of Sofugan . The almost round island has a diameter of 2.7 km and an area of 4.79 km² and reaches a height of 394 m with the Iō-zan (outdated also Iwo-zan; 硫 黄山 , German "sulfur mountain ") the sea. Torishima represents the summit of a stratovolcano that has had numerous eruptions in recent times , most recently in 2002. The current appearance of the island with its vegetation-free cone is the result of an eruption in 1939. Torishima was inhabited (main town: Tamakisato) until all 125 inhabitants died in an eruption in August 1902. By the ejection of ash and phreatomagmatic explosions all the houses were destroyed; there were also submarine eruptions in the vicinity of the island. A later established meteorological station was abandoned in November 1965 after a series of earthquakes ; its ruins are still present at Hatsune Cape ( 初 寝 崎 , Hatsune-zaki ) in the west of the island.
The island is an important breeding area for seabirds , especially the short-tailed albatross ( Phoebastria albatrus ) and the black-footed albatross ( Phoebastria nigripes ), and part of the Fuji-Hakone-Izu National Park . Torishima is a bird sanctuary and may only be entered with permission and only for scientific purposes.
