Details for: Azumayama
The symmetrical cone of Azuma Ko-Fuji, truncated by a 300-m-wide crater, is one of many volcanic features of the Azuma volcanic complex. The Azuma volcano group consists of a cluster of stratovolcanoes, shield volcanoes, lava domes, and pyroclastic cones. Volcanic activity has migrated to the east, with the Higashi-Azuma volcano group being the youngest. This photo was taken from the NW on the flanks of Issaikyo-yama, which has been the site of all historical eruptions (mostly small phreatic explosions) from the Azuma complex.
