Geological summary
The complex andesitic Balbi stratovolcano on Bougainville Island includes a large number of coalesced cones and lava domes. Five well-preserved craters occupy a NW-SE-trending ridge north of the summit cone, which also contains a crater. Three large valleys with steep headwalls dissect the flanks. The age of the most recent eruption is not known precisely. An oral tradition of a major eruption during the 19th century is thought to be in error, but could refer to minor eruptive activity. Fumaroles are located within 600-m-wide Crater B and on its W flank.
