| One of several Japanese volcanoes named Yake-yama ("Burning Mountain"), Akita-Yake-yama is the most recently active of a group of coalescing volcanoes in NW Honshu immediately west of Hachimantai volcano. The main volcano, Yake-yama, contains a small lava dome in its 600-m-wide summit crater. Tsugamori volcano to the east is a stratovolcano of roughly the same height as Yake-yama and has a 2-km-wide crater breached to the NE. The flat-topped parasitic lava dome of Kuroshimori lies 4 km south of Yake-dake. Tamagawa Spa at the western foot, one of several thermal areas, is strongly radioactive. The last magmatic eruption at Akita-Yake-yama formed the Onigajo lava dome in the summit crater about 5000 years ago. The only known historical activity has consisted of somewhat uncertain 19th-century eruptions and mild phreatic eruptions in the 20th century. | |||
