The Kuju volcano group in northern Kyushu consists of more than ten cones and lava domes NE of Aso caldera. This view from the E shows Mimatayama (right) and Nakadake (left) lava domes, which formed about 10,000-12,000 years ago. Fumarolic activity is seen here in 1994 on the flank of Hosshozan (center), the site of small phreatic explosions in November 1995. Many hot springs and hydrothermal fields are located at the Kuju complex.
