Global Volcanism Program | Image GVP-10562

Oshima-Oshima volcano is seen here from the N with Kanpodake, with the cone in the center that formed following the 1741 eruption. Major edifice collapse that year produced a large horseshoe-shaped crater open to the north, with the walls visible at the sides of the image. The 4-km-wide island is 55 km W of the SW tip of Hokkaido, and is the emergent summit of two coalescing volcanoes: Higashiyama at the eastern end of the island, and Nishiyama at the western end.
