The steep topography at the right is the eastern rim of a scarp created by the 1888 collapse of Kobandaisan, one of a group of cones forming Bandaisan volcano. The two lakes in the distance, Onogawa (left) and Akimoto (right) formed after the resulting debris avalanche blocked river drainages. The caldera walls expose a stratigraphy of pyroclastic deposits overlain by thick lava flows. Photo by Lee Siebert, 1988 (Smithsonian Institution).
