Aira Caldera is almost rectangular in shape related to local faulting and was created in a series of large scale of pyroclastic surges that contributed to the Shirasu-Daichi pyroclastic plateau with the last now dated to 29,428 to 30,148 years calibrated before present [7] [1] [2] although earlier work had the date at ~22,000 years ago with ...
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.
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 ...

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.
The Long Valley Caldera in California is about 10 miles wide. And one of the most famous calderas in the world, at Yellowstone National Park, measures 30 miles by 45 miles, according to the U.S ...
Sakurajima is a modern active vent of the same Aira caldera volcano. Sakurajima was formed by later activity within the caldera, beginning about 13,000 years ago. [10] It is about 8 km (5 mi) south of the centre of the caldera. Its first eruption in recorded history was in 963 AD. [11]
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.
The volcano also erupted in June about a mile south of Kilauea caldera, marking the first eruption in that region of the volcano in about 50 years. The last one took place in December 1974. The ...
