Details for: Rishirizan

Rishiri volcano is a highly dissected stratovolcano that forms an island off the NW tip of Hokkaido. The composite cone (center) and flank scoria cones (middle ground) are mirrored on the surface of a maar on the lower south flank. The stratovolcano was constructed during the Pleistocene. Scoria cones and maars on the lower flanks erupted 30,000-8,000 years ago. Photo by Yoshihiro Ishizuka, 1993 (Hokkaido University).
