抄録

The greater parts of aphanitic dark grey Togawa lava occur in underground. Its areal distribution is estimated about 40 km2 mainly by boring data. Akai volcano is the source of Togawa lava and mainly consists of reddish scoria. It has a crater about 0.5km, across, the floor of which is cultivated. Akai volcano has first erupted a lava flow and then formed a small cinder cone. Akai volcano is closely connected with the neighbouring Oomine volcano in types of volcanic structure and eruptive activity. Akai and Oomine volcanoes may be regarded as parasitic cones of Aso gigantic caldera volcano.
