BackgroundThe Dorobu caldera, 13 x 6 km in diameter, is located within the southern part of NE Honshu about 10 km W of Takaharayama volcano. Miura and Tamai (1998) note that many other volcanoes formed during the late Miocene-Pliocene are within a 40 x 40 km area known as the Minami-Aizu geothermal field, including Okukinu, Kawaji, Yunishigawa, Tokusa, Yaso, Sannotoge, and Furumachi. Based on K-Ar ages, Dorobu is thought to have been active from the early Pliocene into the Pleistocene (5.59-1.79 Ma).
