The 11-km-wide lake-filled Towada caldera, whose far northern wall is seen here in the distance, formed during a series of major explosive eruptions over a 40,000-year period ending about 13,000 years ago. The peninsula across the center of the photo is the rim of Nakanoumi caldera that formed by the collapse of Goshikiiwa volcano. The Ogurayama dome to the upper right was the source of the 915 CE eruption. Photo by Yukio Hayakawa (Gunma University).
