The 1635 m high stratovolcano fo Gamkonora is the highest peak on Halmahera.
It has had shifting shifting eruption centers that have produced an elongated series of summit craters along a N-S trending rift. Young-looking lava flows originate near the cones of Gunung Alon and Popolojo, south of Gamkonora.
Since its first recorded eruption in the 16th century, Gamkonora has typically produced small-to-moderate explosive eruptions. Its largest historical eruption, in 1673, was accompanied by tsunamis that inundated villages and killed many people.
