stratovolcanoes
Adatara volcano is located 15 km SW of Fukushima City. The summit is Minowa-yama. The volcano consists of an elongated chain (N-S direction).
The geologic history of the volcano is divided into three stages. In the first stage, lava flows and pyroclastic flows erupted to form the Maegatake cone. The old Osyozan cone was formed in the second stage by eruption of lava flows and pyroclastic flows. In the third stage, eruptions of large amounts of lava
flows, pyroclastic flows and lava domes of andesitic magma formed the main volcanic chain.
