The Aira Caldera is one of the larger recent supervolcanic eruptions to have occurred on our planet. With it roaring to life in a spectacular fashion at some point around 30,000 years ago. This massive eruption formed a pyroclastic flow that was over 800 cubic kilometers in size, and released an additional 300 cubic kilometers worth of tephra ontop of this, at a minimum, too. It covered nearby Japan in a layer of ash, and further plunged the already freezing planet into an ever deeper cold spell, due to the commencement of a volcanic winter, post eruption.

Nowadays this volcano is still very much active, and alive, and it's been embodied by the sukurajima stratovolcano. Which took over after the aira caldera eruption occurred, and it itself formed around 26,000 years ago. This is one of the most active volcanic structures to exist in Japan, but thankfully, recently, that has encompassed small, and somewhat tolerable eruptions... For now.
