Chirinkotan (Russian: Чиринкотан; Japanese 知林古丹島; Chirinkotan-tō) is an uninhabited volcanic island located in the centre of the Kuril Islands chain in the Sea of Okhotsk in the northwest Pacific Ocean. Its name is derived from the Ainu language for "mudslide". It is located 30 kilometers west of Ekarma, its nearest neighbor.

Geology

Chirinkotan is at the far end of a volcanic chain extending nearly 50 km west of the central part of the main Kuril Islands arc. The island is the top of a partially submerged stratovolcano rising approximately 3000 meters from the floor of the Sea of Okhotsk, and is roughly circular with an area of 6 km² [1] The island’s highest point (“Masaochi” in Ainu) is 742 meters high, is still active volcano with major eruptions recorded in 1760, 1884, 1900, 1979, 1986 and 2004. Reports of a 1955 eruption are unconfirmed. The caldera is approximately one kilometer wide, with a depth of 300 to 400 meters, and is breached on its south-east side. The shores of the island are steep cliffs, making landing by small boat impossible.

History

Chirinkotan has had no permanent habitation. Claimed by the Empire of Russia, sovereignty was passed to the Empire of Japan per the Treaty of Saint Petersburg (1875) along with the rest of the Kurile Islands. The island was formerly administered as part of Shumushu District of Nemuro Subprefecture of Hokkaidō. After World War II, the island came under the control of the Soviet Union, and is now administered as part of the Sakhalin Oblast of the Russian Federation.
