|The 9 x 5 km island of Nakano-shima is surrounded by coral reefs. A flat plateau separates an older dissected volcano on the south from the active andesitic cone of On-take, which forms the northern half of the island. On-take contains a summit crater that is filled with water during the rainy season. Sulfur deposits were mined at a SE-flank solfatara until 1944. Only very minor activity has been reported in historical time. A small mud eruption took place in 1914 at the summit crater, and "smoking" increased in 1949.|
