Bandai volcano (Bandai-san), one of Japan's most known active volcanoes, is an complex andesitic stratovolcano rising above the north shore of Lake Inawashiro.
The volcano is located in the southern part of the NE Honshu volcanic arc.
The last magma was erupted at Bandai about 25,000 years ago, but during the past 5000 years, 4 major phreatic explosions have occurred at the volcano. 2 of them occurred in historical time, in 806 and 1888.
In 1888, the youngest edifice of Bandai, Ko-Bandai, collapsed in a catastrophic way after a large phreatic eruption, producing a debris avalanche that buried several villages and formed several large lakes. Seen from the south, Bandai presents a conical profile, but much of the north side of the volcano is missing as a result of the collapse of Ko-Bandai volcano during the 1888 eruption.
