Kikai Caldera was the source of the Akahoya eruption, one of the largest eruptions during the Holocene (10,000 years ago to present). Scientists have discovered a giant dome of lava beneath the Kikai Caldera supervolcano. The volcano is a part of Kikai caldera, the source of one of the world's largest Holocene eruptions about 6 300 years. The experts predict that the Kikai volcano, located just south of mainland Kagoshima Prefecture in southern Kyushu, will be the culprit for the massive eruption.

Iwodake (Iwojima) Kikai Caldera was the site of the VEI 7 Kikai-Akahoya eruption, one of the largest eruptions in the last 10,000 years, paralleling the more famous but less powerful eruption of Krakatau in 1883 in that massive pyroclastic flows travelled across the sea, devastating mainland settlements. The Kikai caldera was created in an active stratovolcano which rests the seabed of the Pacific. The 6.5 ka caldera-forming eruption from the Kikai volcano devastatingly damaged to prehistoric human activities of southern Kyushu, Japan. Given that a huge caldera was formed in shallow sea area during the eruption, a tsunami must have been generated by a sea-level change associated. Outline of 7.3 ka Kikai eruption Kikai Caldera is a Quaternary volcano located in the East China Sea, southern Kyushu (Fig.1a). The Kikai Caldera super-eruption could wipe out 100 million peple The volcano sits only 50km south of Kyushu – Japan ’s main island. The caldera is 17 kmwide and 20 km long. The relationship between tsunamis and scales of caldera collapse during a 7.3 ka eruption of the Kikai volcano were numerically investigated, and a … Kikai Volcano / Mt. Kikai Caldera was the source of the Akahoya eruption, one of the largest eruptions during the Holocene (10,000 years ago to present). The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time it erupted more than 1,000 cubic kilometers (240 cubic miles) of material. Growth of the dome has produced pyroclastic flows as recently as the 2001—they can be identified in this image. It's one of Mexico's most active volcanoes. The eruption comes just three hours after a short-lived, high-level eruption at Ibu volcano, Halmahera. Data is reported through the last data update (9 December 2021).

Japanese volcanologists say they have found evidence of a massive eruption at Kikai Caldera 7000 years ago, and another one 95,000 years ago. Volcanic eruptions can have a significant influence on adjacent ecosystems; however, little is known about the long-term vegetation change related to eruptions. It was the source of one of the world's largest Holocene eruptions about 6,300 years ago when rhyolitic pyroclastic flows traveled across the sea for a total distance of 100 km to southern Kyushu, and ashfall reached the northern Japanese island of Hokkaido.

Around 7,300 years ago, the monstrous Akahoya eruption of the 19-kilometer-wide Kikai Caldera provoked a series of earthquakes and tsunamis, spewing a pyroclastic flow of destructive ash, lava, and gases that swept across the sea to strike the mainland during Japan’s prehistoric Jomon period. The mechanism behind this and how to predict this event are urgent questions. It is possible that currently a giant magma buildup may exist under the Kikai Caldera. did notdiscuss theevolutionof this eruption indetail.In this paper, the 7.3 ka caldera-forming eruption of Kikai volcano is reconstructed based on analyses of the stratigraphy, textural, and lithofacies characteristics, and components of the pyroclastic deposits (mainly in proximal areas), which are useful qualitative indicators Younger cones have grown inside the caldera, including Iwo-dake, a rhyolitic lava dome at the eastern end of Tokara-Iwo-jima.

Japan is a country known for its frequent volcanic eruptions. The Kikai Caldera, located to the south of Japan's main islands, devastated a large swathe of the Japanese archipelago when it spewed upwards of 500 cubic kilometres (120 cubic miles) of magma during the Akahoya eruption some 7,000 years ago – and scientists have just confirmed evidence of new volcanic activity under the crater. Our expert volcanologists and photographers offer unique travel experiences: volcano expeditions, photo tours, and relaxed walking & study tours. 5,365 died, 14,224 were injured, and damages exceeded $200 billion in the area. The erup-tion produced ignimbrite and co-ignimbrite ash which dev-astated prehistoric human settlements of southern Kyushu (Machida and Arai, 1978, 2003). Only four eruptions in the last 10,000 years have been assigned a Volcanic Explosivity Index of 7. Geological Summary. Krakatau eruption and the 3.6 ka Santorini eruption [ Carey et al.,1996;McCoy and Heiken, 2000].

Could a Massive Volcanic Eruption Strike Again? The 2137 eruption of Kikai Caldera was a violent VEI 8 rated Ultra-Plinian rated eruption. An eruption like this would see over 40 cubic kilometers of magma released in one burst, causing enormous damage. Eruptions since 6,300 years ago have been bimodal with several silicic vents and one basalt vent forming. The Alert Level remained at 2 (on a 5-level scale). They chose this volcano for two main reasons. influences of the volcanic eruption on the Holocene vegetational history in Yaku shima. An eruption at 0609 on 29 April at Satsuma Iwo-jima, a subaerial part of Kikai’s NW caldera rim, generated a volcanic plume that rose 1 km above the crater. Occurring underwater, it lead to extreme lahars, and part of the mountain collapsed into a huge pyroclastic surge, which wiped nearby areas off the map, as well as causing a 20 meter tsunami. The eruption produced about 150 km³ of tephra, giving it a Volcanic Explosivity Index of 7 and making it one of the most explosive in the last 10,000 years, ranking alongside the eruptions of Santorini, Changbaishan, Crater Lake, Kurile Lake, Samalas and Tambora. The 2137 eruption of the Kikai Caldera was a violent VEI 8 rated Ultra-Plinian rated eruption.
