Nishinoshima (Japanese: 西之島, "western island") is a volcanic island located around 940 km (584 mi) south-southeast of Tokyo that is part of the Volcano Islands arc. . Nishinoshima is located about 130 km to the west of the nearest inhabited Ogasawara islands, Chichijima Island, hence the name; the other Ogasawara island groups are aligned more to the north–
Mount Fuji. Mount Fuji is a dormant volcano which is the tallest peak in Japan.The latest eruption of Mount Fuji was triggered by an earthquake in 1707. [1] The mountain as it appears now is known as the "New Fuji volcano", which began to erupt about 10,000 years ago.
After a relatively short pause, eruptions began again which formed Komitake Volcano in the same location. These eruptions ended 100,000 years ago. Ashitake Volcano was active from 400,000 to 100,000 years ago and is located 20 km (12 mi) southeast of Mount Fuji.
It is assumed that, much like the 1707 Hōei eruption, the volcano would almost certainly erupt at the same vent where the previous eruption occurred. [6] A repeat of the 1707 Hōei eruption may impact over 30 million people in the highly populated areas of eastern Tokyo, Kanagawa, Chiba and parts of Yamanashi, Saitama, and Shizuoka. [20]
The pyroclastic flow reaches almost the whole area of Kyushu, and volcanic ash is deposited over 15 cm in a wide area from Kyushu to southern Hokkaido. There are three VEI-7 volcanoes in Japan. These are the Aira Caldera, Kikai Caldera and Aso Caldera. Mount Aso is the largest active volcano in Japan. Mount Aso had four eruptions 300,000 to ...

Since then it has undergone more eruptions, the most powerful of which resulted in the appearance and disappearance of a small island.
1986 Izu Ōshima eruption. Mount Mihara's major eruption in 1986 saw lava fountains up to 1.6 kilometres (1.0 mi) high. The eruption had a Volcanic Explosivity Index of 3, and involved a central vent eruption, radial fissure eruption, explosive eruption, lava flows, and a lava lake eruption. There was also a 16 km high subplinian plume. All of ...
