Chokaisan is the largest of the NE Honshu volcanoes, seen here from the NE. The volcano is comprised of two main overlapping edifices, the younger eastern area contains the large horseshoe-shaped caldera that was the source of the Kisakata debris avalanche, seen here opening to the N. Smaller cones later filled much of the area near the rear scarp of the caldera. Photo courtesy Ichio Moriya (Kanazawa University).
