Mount Gamkonora

Gamkonora

Stratovolcano · Indonesia · 1635m

Gamkonora volcano, seen here from the NW coast near Gamsungi village, is one of Halmahera's more active volcanoes. The summit crater of Gamkonora is elongated in a N-S direction, with a small crater lake at the north end. The first two historical eruptions, in 1564 or 1565, and in 1693, were the most severe, producing respectively a destructive lava flow that reached the sea, and a tsunami that inundated villages.

Geological summary

The shifting of eruption centers on Gamkonora, the highest peak of Halmahera, has produced an elongated series of summit craters along a N-S trending rift. Youthful-looking lava flows originate near the cones of Gunung Alon and Popolojo, south of Gamkonora. Since its first recorded eruption in the 16th century, typical activity has been small-to-moderate explosive eruptions. Its largest recorded eruption, in 1673, was accompanied by tsunamis that inundated villages.
