Kikai Caldera (三島村)

Kikai Caldera (鬼界カルデラ Kikai karudera) is a massive, mostly submerged caldera up to 19 kilometres (12 mi) in diameter in the Ōsumi Islands of Kagoshima Prefecture, Japan. It is the remains of the ancient eruption of a gigantic volcano.
Kikai Caldera was the source of the Akahoya eruption, one of the largest eruptions during the Holocene.
Kikai is still an active volcano. Minor eruptions occur frequently on Mount Iō (硫黄岳 Iō-dake), one of the post-caldera subaerial volcanic peaks on Iōjima (硫黄島 Iō-jima). Iōjima is one of three volcanic islands, two of which lie on the caldera rim. On June 4, 2013, weak tremors were recorded. Shortly after, eruptions began and continued off-and-on for several hours.
