![]() ![]() Volcanic activity at Kita-dake ended around 4,900 years ago: later eruptions have been centered on Minami-dake. Most of its eruptions are Strombolian, affecting only the summit areas, but larger Plinian eruptions have occurred in 1471–1476, 1779–17. Its first eruption in recorded history was in 963 AD. It is about 8 km (5 mi) south of the centre of the caldera. Sakurajima was formed by later activity within the caldera, beginning about 13,000 years ago. Sakurajima is a modern active vent of the same Aira caldera volcano. Tephra fell as far as 1,000 km (620 mi) from the volcano. The resulting caldera is over 20 km (12 mi) across. Several hundred cubic kilometres of ash and pumice were ejected, causing the magma chamber underneath the erupting vents to collapse. 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. History Geological history A map of Sakurajima in 1902, showing it as a distinct island. Sakurajima has many natural areas and the ecosystems in different areas where recent eruptions have taken place have been researched as an example of ecological succession. It is a tourist destination known for its onsen, local pottery made from volcanic ash, and produce such as the Sakurajima daikon radish and Sakurajima komikan orange which grow in the immensely fertile volcanic soil. It is serviced by the Sakurajima Ferry which runs 24/7. Sakurajima has a population of a few thousand residents, formerly incorporated as Sakurajima town, with a number of schools, shrines, and shops on the island. The surface of this volcanic peninsula is about 77 km 2 (30 sq mi). The former island is part of the city of Kagoshima which is only 4km across the bay. The mountain is in a part of Kagoshima Bay known as Kinkō-wan. Kita-dake is Sakurajima's highest peak, rising to 1,117 m (3,665 ft) above sea level. Its summit has three peaks, Kita-dake (northern peak), Naka-dake ( central peak) and Minami-dake (southern peak) which is active now. On September 13, 2016, a team of experts from Bristol University and the Sakurajima Volcano Research Centre in Japan suggested that the volcano could have a major eruption within 30 years since then two eruptions have occurred. Earlier eruptions built the white sand highlands in the region. Īs of April 2021, the volcanic activity still continues, dropping volcanic ash on the surroundings. The lava flows of the 1914 eruption connected it with the Ōsumi Peninsula. Sakurajima ( Japanese: 桜島, literally " Cherry Blossom Island") is an active stratovolcano, formerly an island and now a peninsula, in Kagoshima Prefecture in Kyushu, Japan. © 2023 NYP Holdings, Inc.Sakurajima (Kagoshima Prefecture) Show map of Kagoshima Prefecture “A new island was formed just north of the explosion site,” a translation of the university report read, noting the new terrain was 100 meters in diameter and was “consisting mainly of rock blocks.” Phreatomagmatic explosions, the technical term for when intense magma ejections interact with water, were seen along with lava jetting more than 50 meters into the air, the scientists reported. The magma-made island - about a kilometer off Iwo Jima, a famous region far south of the nation’s mainland that’s known for its siege at the end of World War II - was believed to have formed on Oct. ![]() Volcano erupts in Iceland after weeks of intense earthquake activity, spewing lava and smokeĭeath toll jumps to 22 following eruption of Marapi volcano in IndonesiaĪsh-covered woman, 19, calls out for help after Indonesian volcano eruptsĪ new mass of land was recently formed off the shores of Japan after an explosive underwater volcano activated at the end of October, according to researchers from the University of Tokyo.
