Beschreibung
Midagahara volcano is a dissected andesitic-to-dacitic stratovolcano. It contains a 4 km wide caldera is believed to be the result of erosion rather than collapse. Inside the caldera, repeated eruptions of lava and pyroclastics formed the Midagahara plateau that was later dissected by the Yu-kawa river.Eruptions in the past 10,000 years have been restricted to small phreatic explosions that formed craters. A minor historical eruption occurred in the 19th century. An earthquake swarm took place in 1990. Hot springs occur in seven locations on the floor of the poorly defined erosional caldera.
