Akita Komaga Take Volcano, Japan

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.

Two calderas partially filled by basaltic cones cut the summit of Akita-Komaga-take volcano.

The larger southern caldera is 1.5 x 3 km wide and has a shallow sloping floor that is drained through a narrow gap cutting the SW caldera rim.

On its northern side the southern caldera borders a smaller more circular 1.2-km-wide caldera, whose rim is breached widely to the NE.

The two calderas were formed following explosive eruptions at the end of the Pleistocene, between about 13,500 and 11,600 years ago.

Two cones, Me-dake and Ko-dake, occupy the NE corner of the southern caldera, whose long axis trends NE-SW.

The highest point of the volcano is a cone within the northern caldera, 1637-m-high Komaga-take (also known as Omae-dake or Oname-dake), which has produced lava flows to the north and east and has a 100-m-wide summit crater.

Small-scale historical eruptions have occurred from cones and fissure vents inside the southern caldera.
