The truncated summit of Gunung Ibu stratovolcano along the NW coast of Halmahera is seen here from the SW at the summit of Gamalama volcano. The broad summit of Gunung Ibu has nested summit craters. The inner crater, 1 km wide and 400 m deep, contains several small crater lakes. Only two eruptions are known from Ibu in historical time, a small explosive eruption from the summit crater in 1911, and another beginning in December 1998.
