Chirinkotan

Stratovolcano · Russia · 724m

The 3-km-wide island of Chirinkotan is the emergent summit of a volcano that rises 3 km from the floor of the Kuril Basin. It lies at the far end of an E-W-trending volcanic chain that extends nearly 50 km W of the central part of the main Kuril Islands arc. Historical eruptions have been recorded here since the 18th century, including one observed by Captain Snow.

Geological summary

The small, mostly unvegetated 3-km-wide island of Chirinkotan occupies the far end of an E-W volcanic chain that extends nearly 50 km W of the central part of the main Kuril Islands arc. It is the emergent summit of a volcano that rises 3000 m from the floor of the Kuril Basin. A small 1-km-wide caldera about 300-400 m deep is open to the SW. Lava flows from a cone within the breached crater reached the shore of the island. Historical eruptions have been recorded since the 18th century. Lava flows were observed by the English fur trader Captain Snow in the 1880s.

From Wikipedia

Chirinkotan 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 3 kilometres west of Ekarma, its nearest neighbor.
