Aira caldera is one of the most active and hazardous calderas in the world. It is home to the Kirishima volcanoes, a group of active volcanoes at the north end of Aira caldera. One of these volcanoes, Shinmoedake, has produced two strong magmato-phreatic eruptions, separated by almost 300 years. Starting in December 2009, active diving and ...

A resurgent dome formed the island of Samosir. Topographic map of Cagar Alam Rawa Danau Caldera in ...
A map of Sakurajima in 1902, showing it as a distinct island. Sakurajima is in the 25 km (15 mi)-wide Aira caldera, which formed in an enormous "blow-out-and-cave-in" eruption around 22,000 years ago. [9] Several hundred cubic kilometres of ash and pumice were ejected, causing the magma chamber underneath the erupting vents to collapse. The ...

A long-quiet yet massive super volcano, dubbed the "Long Valley Caldera," has the potential to unleash a fiery hell across the planet, and the magma-filled mountain has a history of doing so.
Kilauea, one of the world's most active volcanoes, began erupting around 2:30 a.m. local time, according to the U.S. Geological Survey.
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.
