The summit of Harunasan is seen here from near Maebashi City, SE of the volcano. It contains a caldera and lava domes inside the caldera and on its rim and flanks. Futatsudake, the peak to the right, was the source of two major explosive eruptions during the 5th and 6th centuries. Photo by Tom Simkin, 1993 (Smithsonian Institution).
