Photo Gallery

The impressive sheer pinnacle of Sofu-gan, seen here from the west, rises 99 m above the sea surface south of Tori-shima volcano. Its dramatic and isolated setting prompted it to also be known as "Lot's Wife Rocks." The basaltic-to-andesitic pinnacle is the remnant of a large stratovolcano that is 28 km wide at its base and rises 2200 m above the sea floor. In 1975 discolored sea water was observed about 500 m north of the rocks.
