The changes in volume for the Aira and Kirishima systems suggest they had different inflation and deflation periods. Between 2009 and 2013, there was evidence of inflation in the Aira system. However, after the 2011 eruption at Kirishima, the Aira system experienced a deflation. This was Aira caldera's only deflation between 2009 and 2013. [15]
A major three phase eruption of the Aira Caldera formed in the first phase the Osumi pumice fall, had a second phase Tsumaya pyroclastic flow and in the third Ito eruption phase produced the widely distributed Aira-Tn tephra that has been dated at 29,428 to 30,148 years calibrated before present.

The Buru Caldera cuts the SW flank of the Witori volcano. [2] Sakurajima, Kyūshū, Japan, is a volcano of the Aira Caldera. The Mount Unzen volcanic complex, East of Nagasaki, Japan, comprises three large stratovolcanoes with complex structures, Kinugasa on the North, Fugen-dake at the East-center, and Kusenbu on the South.
Two of the four eruptions were previously identified: Mount Tambora in Indonesia exploded in 1815, and Cosegüina erupted in Nicaragua in 1835. The volcano that produced the 1808/1809 eruption ...

Approximately 760,000 years ago, this super volcano in particular had a massive eruption on an apocalyptic scale that blanketed the United States region in molten lava and ash.
A volcano that once existed in the northern part of Kagoshima Bay caused an eruption called the Great Aira Eruption about 25,000 years ago, forming the Aira Caldera. Aira City is located on the northwest side of this caldera, on the somma, and there is a stratum called Shirasu, which originated from pyroclastic flows that flowed out during a ...
