Background

Futamata-yama is a late Pleistocene (about 140,000 or 90,000 years old) stratovolcano and lava dome (Nakano et al., 2001-). A thick lava flow extends to the NW. It is located within the Quaternary Tonohetsuri caldera (Yamamoto, 1995; 2007). The oval-shaped Narioka caldera cuts the western rim of Tonohetsuri caldera and the western rim of the older Ono caldera. These large calderas were formed during eruption of the Kumado, Ashino, and Nishigo pyroclastic flows about 1.4, 1.2, and 1.0 million years ago, respectively.
