Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Ata
Symmetrical Kaimon volcano is the youngest and most prominent feature of the Ibusuki volcanic field at the southern tip of Kyushu. The 922-m-high stratovolcano, seen here from the north, was built during the last 4000 years and has produced all the historical eruptions of the volcanic field. The Ibusuki field, located west of the Pleistocene Ata caldera, contains numerous small central cones, maars, and the 4.5-km-wide Ikedo-ko caldera. The latest eruptions of Kaimon took place during the 9th century. Photo by Lee Siebert, 1988 (Smithsonian Institution).
