SfondoSanbe volcano is a complex of 7 volcanic centers of dacitic-to-andesitic composition at the northern end of the complex. Sanbe has had several large explosive eruptions during the Pleistocene and one strong Holocene eruption from Taihei-zan lava dome about 3700 years ago. This eruption was accompanied by pyroclastic flows that swept down the NE-to-SE flanks and traveled 9 km down the Hayamizu River to the SW. Younger, undated eruptions have also occurred (Machida and Arai, 1992).
