Mount Gamkonora, Stratovolcano in West Halmahera Regency, Indonesia

Mount Gamkonora is a stratovolcano on Halmahera island, Indonesia, reaching 1,560 metres (5,118 ft), the highest peak on the island. Its eruptions have produced an elongated series of craters running north to south along a rift.

The largest eruption, rated VEI-5, occurred on 20 May 1673 and was accompanied by a tsunami that inundated nearby villages. Between 1564 and 1989 the volcano erupted twelve times, and it erupted again on 10 July 2007, when over 8,000 people fled their homes in the vicinity.

The name Gamkonora is used for the mountain and for the district of Ibu in West Halmahera where it stands. Villages near the slopes were inundated by the 1673 tsunami, and in 2007 more than 8,000 residents left their homes during the eruption.

The summit sits at 1,560 metres in Ibu district, West Halmahera Regency, on Halmahera island. Access is by road from nearby towns, and the climb crosses terrain shaped by the north–south chain of craters. Because the volcano is active, check conditions with local authorities before setting out.

Its 1673 eruption reached VEI-5, the strongest in a series of thirteen recorded events between 1564 and 1989, and the resulting tsunami destroyed villages around the mountain. The elongated north–south chain of craters marks the rift along which these vents opened.
