Kikai is a mostly submerged 19-km-wide caldera S of Kyushu that was the source of one of the world's largest Holocene eruptions about 6,300 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 Iwodake cone shows the W rim of Kikai caldera forming the peninsula (upper left) behind the Inamuradake scoria cone.
