Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Bagana
Plumes rise from a slow-moving andesite lava flow descending the NW flank of Bagana on 26 April 1988. The flow at that time had been moving for about 3 or 4 years and is typical of the lava extrusion that began in 1972. This volcano was largely constructed by an accumulation of viscous andesite lava flows like this one. Photo by Wally Johnson, 1988 (Australia Bureau of Mineral Resources).

Bagana volcano, in a remote portion of central Bougainville Island, is frequently active. This massive symmetrical cone was largely constructed by an accumulation of viscous andesitic lava flows. The entire edifice could have been constructed in about 300 years at its present rate of lava production. Eruptive activity is characterized by non-explosive effusion of viscous lava that maintains a small lava dome in the summit crater, although occasional explosive activity produces pyroclastic flows. Lava flows with tongue-shaped lobes up to 50 m thick and prominent levees descend the flanks on all sides.
