It rises from an ocean floor with a depth of between 300 and 400 meters. The island has a roughly circular coastline of approximately 52 kilometers in length. The highest elevation, , is an active volcano with a height of 758 meters. The mountain has been recorded to have erupted numerous times through history and is mentioned as far back as Nara period written records. Major eruptions occurred in 1965 and 1986, each forcing the temporary evacuation of the inhabitants. The last recorded eruption was in 1990. The epicenter of the 1923 Great Kantō earthquake, which devastated Tokyo and the surrounding region, was deep beneath Izu Ōshima Island.
