Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Nantaisan
The Nantai cone on the right horizon rises above Yunoko lake and the Senjogahara plain (right center). Lava flows from the early stage of the construction of Nantaisan dammed up the Daiyo River, forming Lake Chuzenji (out of view to the right). A collapse scar is visible on the N (left) side of the volcano. The latest effusive activity of Nantai produced the Osawa lava flow, which traveled from the crater down the N flank.

Nantaisan stratovolcano rises above the north shore of Lake Chuzenji in Nikko National Park, and forms a backdrop to the temple complex there. Lava flows from the early stage of edifice construction dammed the Daiyo River, forming Lake Chuzenji; the Kegon waterfall plunges over this barrier. Nantaisan has an asymmetrical profile when viewed from the west as a result of late-stage collapse on the north side. Two major late-stage eruptions ejected large amounts of scoria, followed by the emission of pyroclastic flows. The latest effusive activity produced the Osawa lava flow, a thick, viscous dacitic flow that traveled from the breached crater down the N flank. The Bentengawara pyroclastic-flow deposit, representing the latest known eruptive activity, was radiocarbon dated at about 10,000 years Before Present and was emplaced following a quiescent period of about 3,000 years.
