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.

지질학적 요약

Nikko-Shiranesan is a relatively small, 2578-m-high andesitic volcano consisting of a group of four lava domes resting on a shield volcano that rises to the NW of scenic Lake Chuzenji in Nikko National Park. All historical eruptions, recorded during the 17th-20th centuries, have consisted of phreatic explosions from Shiranesan, the youngest lava dome. Viscous lava flows with prominent levees from the underlying shield volcano Keizukayama were responsible for the formation of several scenic lakes north of the volcano.
