Mt. Mihara is a scoria cone about 150m high, 800m in diameter at its summit and 1,200m in diameter at its base, a "Central Cone" formed in the caldera at the summit of Izu Oshima Volcano. During the Great An'ei Eruption of 1777-78, a huge amount of magma spray and large volcanic bombs fell on the mountain, giving it its present appearance.
The black streaks on the slopes of Mt Mihara are the remains of lava flows from the 1986 eruption.
