Details for: Akita-Komagatake
Omae-dake cone and the small pond Amida-ike are located at the NE end of the summit crater complex of Akita-Komaga-take volcano. The pyroclastic cone Omae-dake (also known as Komaga-take) forms the highest point of the volcano and has produced lava flows to the north and east. This photo is taken from the NE rim of an elliptical 1.5 x 3 km caldera partially filled by basaltic cones. Historical eruptions have occurred from cones and fissure vents inside the caldera.
