UhrzeitMag. / TiefeDistanceOrt
Akita-Komaga-take volcano is an active volcano in northern Honshu. It is located 10 km east of Tazawa Lake, near the border of Akita and Iwate prefectures, and forms the southern extremity of the Towada-Hachimantai National Park.
The volcano consists of a main edifice cut by 2 calderas that formed after 2 large explosive eruptions between 11,600 and 13,500 years ago. The calderas are partially filled by younger cones. Historic activity consists of small eruptions from cones and fissure vents inside the southern caldera.
It is suspected that Akita-Komaga-take's eruptions are often not preceded by much seismic activity, as was the case during the last eruption, in 1970.

Beschreibung:

The larger southern caldera of Akita-Komaga-take is NE-SW elongated and 1.5 x 3 km wide. It contains the younger cones Me-dake and Ko-dake in the NW corner, the Komaga-take cone (also known as Omae-dake or Oname-dake) in the center, and the small pond Amida-ike. Its floor dips to the SW where it is drained by a narrow gap. Komaga-take has erupted lava flows to the north and east. It contains a 100-m-wide summit crater.
The adjacent smaller northern caldera is 1.2 km wide, more circular and widely breached to the NE. It contains a cone forming the highest point of the volcano.

1970-71 eruption
Akita-Komaga-take volcano erupted from 18 September 1970 until 25 January. The eruption produced strombolian activity and lava flows from Medake cone in the southern caldera. It was the first eruption in 38 years and the first in historic times to produce lava flows. ...mehr

1962 earthquakes
A seismic swarm occurred at Komagatake volcano around 10 December 1962. 4 felt earthquakes up to magnitude 4 accompanied by subterranean rumbling at the northwestern foot of the mountain were recorded.

1932 July eruption
Akita-Komaga-take volcano erupted from 21-24 July 1932 from Ishibora crater 500 m south of Me-dake. Explosions formed 11 small craters on a 600 m long NE-SW fracture. Ash destroyed vegetation in up to 2 km distance on Mt. Yokodake at the eastern rim of the caldera. Light ash fall also occurred around the towns of Hashiba and Shizukuishi.
