Suwanose-jima (諏訪之瀬島) volcano is Japan's and one of the world's most active volcanoes. It has been in a state of near-continuous strombolian-type eruption since 1949.
The volcano forms the 8 km long spindle-shaped island of the same name in northern Ryuku Islands, Japan. The remote island is home to about 50 residents only.
Suwanose-jima consists of an andesitic stratovolcano with 2 historically active summit craters. Intermittent to continuous strombolian activity began from On-take (Otake), the NE summit crater, in 1949 and has been going on since. After 1996, occasional periods of inactivity have become more frequent.

Beschreibung
The summit of Suwanose-jima volcano is truncated by a large breached crater extending to the sea on the east flank that was formed by edifice collapse.The largest historical eruption took place in 1813-14, when thick scoria deposits blanketed residential areas, and the SW crater produced 2 lava flows that reached the western coast. At the end of the eruption the summit of On-take collapsed forming a large debris avalanche and creating the horseshoe-shaped Sakuchi caldera, which extends to the eastern coast. The island remained uninhabited for about 70 years after the 1813-1814 eruption. Lava flows reached the eastern coast of the island in 1884.
