1986-12-01 · Geology of the Aira caldera The Aira caldera is located in the northern part of Kagoshima Bay and is bounded by the Sakurajima post-caldera volcano, which had been an island. The historical eruptions of the volcano date back to the 8th century and the volcano island was connected with the Oosumi Peninsula in 1914 by lava flows.

Japan. Jour. 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 ().

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

Eruption of voluminous pyroclastic flows accompanied the formation of the 17 × 23 km 2013-01-28 · Sakurajima's present day volcano is a new volcanic cone inside the 17 x 23 km wide Aira caldera forming the northern half of Kagoshima Bay. The caldera formed around 22,000 years ago during a Plinian eruption that produced large pyroclastic flows. Around 13,000 years ago, another smaller caldera 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 km³) followed by oxidized, fine-grained Tsumaya pyroclastic flow (13 km³), both erupted from a vent located at the present site of 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 ). 2017-06-06 · The Aira caldera in the northern half of Kagoshima Bay contains the post-caldera Sakurajima volcano, one of Japan's most active. Eruption of the voluminous Ito pyroclastic flow accompanied formation of the 17 x 23 km (10.5 x 14.3 miles) caldera about 22 000 years ago.

the center ofthe Aira caldera. Isopach maps with a proposed yent inside the Aira caldera were published by OTA et al. (1967) and SuGAwARA (1974). Howevrer, ARAMAKI and UI (1966) and ARAMAKi (1983) maintained that their isopachs point to a probable vent located at the present site of Sakurajima volcano, an active post-caldera stratocone situated

Aira caldera, one of the most active and hazardous volcanoes in South Japan, is associated with an active cone, Sakurajima (Fig. 2a).The activity of Sakurajima, characterized by frequent (daily 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. This deflation, Aira Caldera. is a gigantic volcanic caldera in the south of the island of Kyūshū, Japan.

Identifying how volcanoes interact is critical to determine if and how an eruption can influence the activity of a distant volcano or raise the threat of a new strong explosive event. 2020-10-01 · English: Aira Caldera in Kagoshima Prefecture, Kyushu, Japan.
