The large crater in the center of the photo was produced on the SE flank of Mount Fuji during the 1707-1708 eruption. This major explosive eruption, one of the largest in Japan during historical time, ejected more than 1 km3 of tephra and resulted in ashfall in the capital city of Edo (Tokyo). Three craters were formed sequentially along a NW-SE-trend from the summit. The primary vent of the eruption was the upper crater (center), which is 750 x 1,500 m in size and 750 m deep from the highest point on the crater rim.
