Iwaki volcano is a large symmetrical stratovolcano and the NW-most active volcano in Honshu, Japan. Because of its shape, it has been called the Fuji-san of the Tsugaru district.
Iwaki contains a 2-km-wide summit crater which is filled by a lava dome flanked by 6explosion craters. 3 lava domes are found on the western and southern flanks of the andesitic volcano. Historical eruptions have been reported at Iwaki since 1600 AD and have consisted primarily of small-to-moderate phreatic explosions.
