Details for: Kikai
Kikai is a mostly submerged, 19-km-wide caldera south of Kyushu that was the source of one of the world's largest Holocene eruptions about 6300 years ago. Pyroclastic flows traveled across the sea for a total distance of 100 km and devastated southern and central Kyushu. This view from near the summit of the post-caldera cone Iwo-dake shows the western rim of Kikai caldera forming the peninsula (upper left) behind conical Inamura-dake scoria cone.
