Details for: Kujusan
The Kuju volcano group in northern Kyushu consists of more than ten andesitic stratovolcanoes and lava domes NE of Aso caldera. This view from the east shows Mimata-yama (right) and Naka-dake (left) lava domes, which formed about 10,000-12,000 years ago. Fumarolic activity is seen here in 1994 on the flank of Hossho-zan (center), the site of small phreatic explosions in November 1995. Many hot springs and hydrothermal fields are located at the Kuju complex. Photo by Yasuo Miyabuchi, 1994 (Forestry and Forest Products Research Institute, Kyushu).
