Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Miyakejima
The craters in the foreground and the lava flow to the right erupted in 1983 from vents on the SW flank of Miyakejima. The 8-km-wide island rises about 1.1 km from the sea floor in the northern Izu Islands, about 200 km SSW of Tokyo. The summit cone of Oyama (upper right) lies within a caldera that formed about 3,000 years ago. Frequent eruptions have occurred since 1085 CE at vents ranging from the summit to below sea level.

The circular, 8-km-wide island of Miyakejima forms a low-angle stratovolcano that rises about 1,100 m from the sea floor in the northern Izu Islands about 200 km SSW of Tokyo. The basaltic volcano is truncated by small summit calderas, one of which, 3.5 km wide, was formed during a major eruption about 2,500 years ago. Numerous craters and vents, including maars near the coast and radially oriented fissure vents, are present on the flanks. Frequent eruptions have been recorded since 1085 CE at vents ranging from the summit to below sea level, causing much damage on this small populated island. After a three-century-long hiatus ending in 1469 CE, activity has been dominated by flank fissure eruptions sometimes accompanied by minor summit eruptions. A 1.6-km-wide summit crater was slowly formed by subsidence during an eruption in 2000.
