Aira Caldera is a gigantic volcanic caldera that is located on the southern end of Kyushu, Japan. It is believed to have been formed over 22,000 years ago from a succession of pyroclastic surges . It is currently the place of residence to over 900,000 people.

1998-02-01 · The Aira caldera, with a size of about 20 km in diameter, is thought to have been formed in close association with the eruptions. Geologic and petrologic studies have revealed a detailed stratigraphic succession of pyroclastic flow deposits, and estimated the chemical and thermal structure of the magma reservoir (e.g., Aramaki and Ui, 1966 ; Kobayashi et al., 1983 ; Tsukui and Aramaki, 1990 ).

The white dotted line is the rim of the Aira Caldera proposed by Matumoto (1943). The white box located in the northeast (Kokubu urban area) of the caldera shows the area used in this study for SAR data analysis and modeling. The black box located in the southwest of the caldera shows the area used to perform the analysis of the spatial structure 2021-2-23 · the Aira Caldera. This simple model predicts a maximum volume increase of 20–30×106 m3 between 1995 and 1998, which would produce an inflation of about 70mm at the cen-tre of the Aira Caldera and 40mm in the Kokubu south urban area. These results are in good agreement with other geo-physical observations carried out on the Aira caldera during Underneath this beautiful, picturesque area lies a hidden danger – a danger that could cause the end of humanity. The end of civilization as we know it. That is because it is part of the beautiful, dangerous, and beautifully dangerous Aira caldera.
