Balbi

Volcano
Balbi is a large stratovolcano and the highest point on Bougainville Island, Northern Solomon Islands, Papua New Guinea. It is not certain whether the volcano has erupted in historic times, as some local traditions suggest. An active fumarole field is located at Balbi's 600 m wide summit crater and on its western flank.

Balbi volcano is a complex andesitic volcano, composed of many craters, lava domes and cinder cones. 5 young craters are along a NW-SE ridge north of the summit cone. 3 large amphitheatre-shaped valleys have been formed by debris avalanches on the southern, NE and northern flanks of the volcano. The largest of these on the northern side is 7 km long, 3 km wide, and 610 m deep.

The volcano is covered with thick forest up to 1300 m elevation, followed by thickets of bamboo dominating 1300 m to 2300 m elevation. Above 2300 m, moss dominates.
