Tarumai volcano was constructed on the SE rim of the 13 x 15 km Shikotsu caldera. The summit has a small 1.5-km-wide caldera that formed during eruptions in 1667 and 1739 CE. It contains a flat-topped summit lava dome that grew in 1909. It has been one of Hokkaido's most active volcanoes in historical time. Two other Holocene post-caldera volcanoes occur at Shikotsu, Fuppushi (adjacent to Tarumai) and Eniwa, on the opposite side of the caldera. Photo by Ichio Moriya (Kanazawa University).
