Yoteizan volcano is seen here to the NW above Lake Toya, which fills the 10-km-wide Toya caldera. The caldera formed during a major eruption about 110,000 years ago. A series of lava domes in the center of the lake form Nakanojima island, whose flank appear in the right-foreground. The photo was taken from the lower flank of Usu volcano, which grew on the southern rim of Toya caldera. Photo by Norm Banks, 1981 (U.S. Geological Survey).
