IEDA / DECADE Detail

Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Hakkodasan

The Hakkoda volcano consists of a group of 14 stratovolcanoes and lava domes south of Mutsu Bay at the northern end of Honshu. The NE rim of an 8-km-wide Pleistocene caldera forms an arcuate ridge across a flat caldera-floor moat NE of the Hakkoda group volcanoes, which bury the SE caldera wall. This view looks from the west towards a northern group of volcanoes, constructed within the caldera. Akakura-dake, Ido-dake, and Hakkoda-Otake (left to right) have well-preserved craters. No historical eruptions are known of the Hakkoda group. Photo by Takashi Kudo, 1996 (Hokkaido University).

Description: Hakkoda volcano is a group of 14 stratovolcanoes and lava domes south of Mutsu Bay at the northern end of Honshu Island, Japan. There are fumaroles and hot springs.

Hazard Description: 3 soldiers were killed by CO2 on 12 July 1997 on a training mission at the N foot of Hakkoda volcano. They had entered a depression filled by lethal concentrations of volcanogenic CO2 (Smithsonian / GVP monthly reports).
