Nikko-Shiranesan is a relatively small volcano consisting of a group of four lava domes in Nikko National Park. An E-W-trending fissure is visible across the summit lava dome, seen here from Mae-Shirane, E of the summit. Eruptions from the 17th to 19th centuries CE consisted of phreatic explosions from Shiranesan, the youngest lava dome. Photo by Lee Siebert, 1964 (Smithsonian Institution).
