Mount Ibu is a stratovolcano at the north-west coast of Halmahera island, Indonesia. The summit is truncated and contains nested craters. The inner crater is wide and deep, while the outer is wide. A large parasitic cone is at the north-east of the summit and a smaller one at the south-west. The latter feeds a lava flow down the west flank. A group of maars are on the western and northern side of the volcano.
