Sintesi geologica

Kuchinoshima, lying in the northern Ryukyu Islands between the volcanic islands of Nakanoshima and Kuchinoerabujima, consists of two andesitic stratovolcanoes and a NW-SE-trending chain of lava domes. Two small villages, Nishinohama and Kuchinoshima, lie at the northern end of the mostly uninhabited island. The compound 628-m-high Maedake lava dome, forming the highest point on the 3 x 7 km wide island, was constructed east of the summit of 501-m-high Yokodake stratovolcano. The last magmatic eruption took place about 1200-1300 years ago.
