A plume rises from the crater of Miharayama on Oshima island. It lies within a 4-km-wide caldera, the rim of which is prominently visible in this aerial photo from the SW. Dark-colored lava flows from the 1986 eruption cover part of the caldera floor north of Miharayama. More than 40 parasitic cones are located within the caldera and along two parallel rift zones trending NNW-SSE across the island. The port city of Motomachi on the west coast is at the left and the island's airport is at the upper left. Photo by Ichio Moriya (Kanazawa University).
