Nakano-shima volcano eruptions: 1949 (uncertain), 1914 (phreatic explosions) Last earthquakes nearby:
The island is surrounded by coral reefs, but unlike older extinct ocean islands that sink and form reefs Nakano-shima's volcano is active. There are no known magmatic eruptions in historic times, but a small mud eruption occurred in 1914, and increased "smoking" was seen in 1949. Background:An older, eroded volcano forms the southern half of the island and a flat plateau separates it from the present-day active volcano which forms the northern half and has an andesitic cone called On-take.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. |
