Oshima is the northernmost of the Izu Islands, seen here from the NW on Sagami Bay. The broad, low volcano forms an 11 x 13 km island and was constructed over the remnants of three older edifices. It contains a 4-km-wide caldera with the central cone of Miharayama, seen producing a small plume in this 1961 photo. Miharayama has been the site of numerous historical eruptions.
