O-Bandai volcano was constructed within a horseshoe-shaped caldera that formed about 40,000 years when an earlier volcano collapsed, forming the Okinajima debris avalanche, which traveled to the southwest and was accompanied by a plinian explosive eruption.
The Kikai Caldera is mostly submarine, with three islands and a few reefs representing part of the caldera rim and central cones.
Toya Caldera lies in the V-shaped intersection of the Kurile and Japan arcs, along both of which the Pacific plate is subducted northwesterly direction beneath the Eurasian plate at a rate of approximately 10 centimeters per year (Circum-Pacific Map Project, Northwest Quadrant Panel, 1981).

Such an eruption erases virtually all life in a radius of hundreds of kilometers from the site, and entire continental regions further out can be buried meters deep in ash.
VEI-8 eruptions are not so great as to form mountains, but instead circular calderas, resulting from the downward collapse of land at the eruption site to fill emptied space in the magma chamber beneath.
The caldera can remain for millions of years after all volcanic activity at the site has died.

Volcanic activity in coastal region is one of the factors greatly responsible for catastrophic coastal change.
Southern Kyushu coastal area presented here is most suitable for constructing a model for catastrophic change in coastal landforms, because some Quaternary gigantic calderas and intra-caldera volcanoes are characteristically developed in the southern Kyushu coastal area.
Its comparison with recent crustal movements of Aira caldera associated with recent volcanic activities of intra-caldera active volcano suggests that magma inflation of Aira caldera has been affected the Holocene upwarping.
