Akita-Yakeyama

Stratovolkan · Japan · 1366 m

Akita-Yakeyama, seen here from the E, is one of several Japanese volcanoes named Yakeyama ("Burning Mountain"). Yakeyama contains a lava dome in its 600-m-wide summit crater and the flat-topped Kuroshimori lava dome is visible to the left. Several thermal areas are located on the lower western flank.

One of several Japanese volcanoes named Yakeyama ("Burning Mountain"), Akita-Yakeyama is the most recently active of a group of coalescing edifices in NW Honshu immediately west of Hachimantai volcano. The main volcano, Yakeyama, contains a small lava dome in its 600-m-wide summit crater. Tsugamori to the east is a stratovolcano of roughly the same height and has a 2-km-wide crater breached to the NE. The flat-topped lava dome of Kuroshimori lies 4 km S of Yakedake. One of several thermal areas, the Tamagawa Spa at the western foot has strongly acidic and slightly radioactive water. The last magmatic eruption formed the Onigajo lava dome in the summit crater about 5000 years ago. There have been somewhat uncertain reported 19th-century eruptions and mild phreatic eruptions in the 20th century.
