Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Osorezan
The SE side of Osore-yama, on the Shimokita Peninsula in northernmost Honshu, rises above Mutsu Bay. Osore-yama contains a 3-km-wide caldera partly occupied by a shallow lake that drains through the north caldera wall. Dissected lava domes ring the caldera floor. The only report of historical activity at Osore-yama was in a Tohoku district travel document published in 1787, which stated that Yake-yama ("Burning Mountain") in Mutsu country (Osore-yama) had erupted.
