Monte Azuma-kofuji

Azumayama

Estratovolcán · Japan · 1949 m

The Azuma Kofuji cone with its 300-m-wide crater is one of many volcanic features of the Azumayama complex. This volcano group consists of a cluster of cones and lava domes. Volcanic activity has migrated to the E, with the Higashi-Azuma volcano group being the youngest. This photo was taken from the NW on the flanks of Issaikyoyama, which has been the site of historical eruptions (mostly small phreatic explosions).

Resumen geológico

The Azumayama volcanic group consists of a cluster of stratovolcanoes, shield volcanoes, lava domes, and pyroclastic cones. The andesitic and basaltic complex was constructed in two E-W rows above a relatively high basement of Tertiary sedimentary rocks and granodiorites west of Fukushima city. Volcanic activity has migrated to the east, with the Higashi-Azuma volcano group being the youngest. The symmetrical Azuma-Kofuji crater and a nearby fumarolic area on the flank of Issaikyo volcano are popular tourist destinations. The Azumayama complex contains several crater lakes, including Goshikinuma and Okenuma. Historical eruptions, mostly small phreatic explosions, have been restricted to Issaikyo volcano at the northern end of the Higashiyama group.
