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.

Kuchino-shima, the small island at the upper right, lies in the northern Ryukyu Islands between the islands of Nakano-shima (left) and Kuchinoerabu-jima. The 3 x 7 km wide island of Kuchino-shima, seen in an aerial perspective from the SE in this computer-generated graphic image, consists of two stratovolcanoes and a NW-SE-trending chain of lava domes. The highest point on the island is 628 m above sea level. The last dated eruption at Kuchino-shima took place about 2850 years ago.

The elongated Kuchino-shima consists of two andesitic stratovolcanoes and a NW-SE-trending chain of lava domes. It is seen here from the NE; two small villages, Nishinohama and Kuchino-shima, lie at the northern end of the mostly uninhabited island. The island consists of two andesitic stratovolcanoes and a NW-SE-trending chain of lava domes. The compound 628-m-high Mae-dake lava dome (left-center) forms the highest point on the 3 x 7 km wide island.

Sharp-topped Mae-dake lava dome, the highest point on Kuchino-shima, was formed during the last magmatic eruption on the island between the 8th and 13th centuries.

The sharp-topped peak in the center is 628-m-high Mae-dake lava dome, which rises above the eastern coast of Kuchino-shima and forms the high point of the island. Flat-topped Yoko-dake peak lies at the upper right. Kuchino-shima, a mostly uninhabited island, lies in the northern Ryukyu Islands between the volcanic islands of Nakano-shima and Kuchinoerabu-jima. It consists of two andesitic stratovolcanoes and a NW-SE-trending chain of lava domes.
