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.
