Sakurajima
Geography
Sakurajima is an active stratovolcano located in Kagoshima Bay, southern Kyushu, Japan. The volcano lies 8 km from the city of Kagoshima, and is a part of the larger Aira caldera. Sakurajima's lava flows are primarily andesitic, and the volcano has been active for thousands of years.
History
The earliest recorded eruption of Sakurajima was in 708 AD. The most powerful eruption in historical times occurred in 1914, which connected the island to the Osumi Peninsula. The 1914 eruption was a VEI-4 event, and caused extensive damage in the region, including the loss of many lives.
Geology
Sakurajima is a composite volcano, composed of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs. The volcano has three peaks: Kitadake, Nakadake, and Minamidake, which is currently the most active.
Eruptions
Sakurajima is one of the most active volcanoes in Japan, with hundreds of minor eruptions occurring each year. The volcano is under constant monitoring by the Japan Meteorological Agency.
Flora and Fauna
Despite its volcanic activity, Sakurajima supports a variety of plant and animal life. The island is known for its production of a large, sweet variety of mandarin orange known as the Sakurajima Komikan.
Impact on Human Life
The city of Kagoshima, with a population of over 600,000, lies in close proximity to Sakurajima. The volcano's activity has a significant impact on the city, with frequent ash fall and the ever-present threat of a major eruption.
