Toshima
About Toshima
The small 2 x 2.4 km island of Toshima is located in the northern Izu Islands south of Izu-Oshima Island about 20 km W of the main volcanic front. Steep cliffs up to 300 m high ring the basaltic to basaltic andesite island on three sides. The summit is asymmetrically located opposite the more gentle slopes of the northern side of the island, where the village of Toshima is located. The latest known eruption of this stratovolcano occurred sometime between about 9,000 and 4,000 years ago, producing a lava flow from Kajiana crater.
