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.

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 ...
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 ...
This is a sortable summary of 27 major eruptions in the last 2000 years with VEI ≥6, implying an average of about 1.3 per century. The count does not include the notable VEI 5 eruptions of Mount St. Helens and Mount Vesuvius. Date uncertainties, tephra volumes, and references are also not included.
Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...
