Details for: Miyakejima
The craters in the foreground and the lava flow at the right were erupted in 1983 from vents on the SW flank of Miyake-jima volcano. The circular, 8-km-wide island of Miyake-jima forms a low-angle stratovolcano that rises about 1100 m from the sea floor in the northern Izu Islands about 200 km SSW of Tokyo. The 815-m-high summit cone of O-yama (upper right) lies within a caldera that formed about 3000 years ago. Frequent historical eruptions have occurred at Miyake-jima since 1085 CE at vents ranging from the summit to below sea level. Photo by Ichio Moriya (Kanazawa University).

Location: Miyakejima (View Details at MaGa DB)
Description: Miyakejima volcano is located in the Pacific, 200 km south of Tokyo, on the of Izu–Mariana active volcanic arc. This area is tectonically active because of the subduction of the Pacific plate beneath the Eurasian plate. It is one of the most active basaltic stratovolcanoes in Japan
