IEDA / DECADE Detail

Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Nakanoshima

Nakano-shima island is seen here from a beach on Kuchino-shima to the NNE. The active andesitic cone on On-take, with a summit crater that fills with water during the rainy season, forms the conical peak at the right. 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 On-take. Only very minor activity has been reported in historical time.
