Rishiri forms an island W of the northern tip of Hokkaido. The main edifice ceased erupting during the Pleistocene and extensive erosion has created a rugged summit flanked by radial ridges. Scoria cones and maars on the lower flanks have been active during the late Pleistocene and early Holocene. Photo by Yoshihiro Ishizuka, 1997 (Hokkaido University).
