About 22,000 years ago a series of large‐scale pyroclastic eruptions produced the Aira caldera 20 km×20 km wide at the northern end of Kagoshima Bay in southern Kyushu. It started with a Plinian pumice eruption (Osumi pumice fall, 98 km 3) followed by oxidized, fine‐grained Tsumaya pyroclastic flow (13 km 3 ), both erupted from a vent located at Aira Caldera. Gigantic volcanic caldera in the south of the island of Kyūshū, Japan.

The sudden destabilization of voluminous magma after stable accumulation in a crustal magma chamber is a key process in the sequence of a catastrophic caldera-forming eruption. We investigated the petrological characteristics of magma that has erupted before, during and after the caldera-forming eruption of the Aira Caldera, Japan. This provides an example of the evolution of a rhyolite magma De Aira-caldera is een 17 x 23 km brede caldera in het zuiden van het Japanse eiland Kyūshū.

Aira caldera

Geol. Soc. The Aira caldera occupies the northern part of Kago-shima Bay. Hayasaka (+321) revealed that the origin of the bay dates back to certain age far older than the formation of the calderas and was attributed to the formation of an elongated depression from north to Aira Caldera (姶良カルデラ, Aira-Karudera?) is a gigantic volcanic caldera in the south of the island of Kyūshū, Japan.The caldera was created by a massive eruption, approximately 22,000 years ago.Eruption of voluminous pyroclastic flows accompanied the formation of the 17 × 23 km-wide Aira caldera. Together with a large pumice fall, these amounted to more than 400 km 3 of tephra (). The location and deformation of Aira caldera.: (a) Aira caldera is situated at the southern end of Kyushu (Japan), indicated by the grey arrow.

It started with a Plinian pumi Aira caldera is located in the northern part of Kagoshima Bay, Kyushu, Japan (Aramaki, 1984; Fig. 1). The post-caldera volcano, Sakurajima, is an andesitic stratovolcano that has been active for the last 13,000 years. Leading up to the eruption of Kirishima, which is located in the densely-populated Kagoshima region, the Aira caldera stopped inflating, which experts took as a sign that the volcano was at rest. Whereas Aira caldera had been inflating steadily for two decades, it deflated during the eruption of Kirishima which started with a large-volume lava extrusion.

日本語: 鹿児島県 の 姶良カルデラ 。 低地のデータの欠損などは修正済み。 Using the example of continued inflation at Aira caldera, Japan, we demonstrate that magma is accumulating faster than it can be erupted, and the current uplift is approaching the level inferred prior to the violent 1914 Plinian eruption. Viscoelastic crustal deformation in the Aira caldera before and after the 1914 eruption of the Sakurajima volcano.
