Based on information from RVO, the Darwin VAAC reported that Balbi erupted on 7 May. Ash was not detected on satellite imagery. [Correction: RVO later confirmed that Balbi did not erupt on 7 May and attributed the reports to thunderstorm activity.]

The large Balbi stratovolcano forms the highest point on Bougainville Island. The 2715-m-high summit of the complex andesitic volcano is part of 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 of the volcano. The age of the most recent eruption of Balbi volcano is not known precisely. An oral tradition of a major eruption during the 19th century is now thought to be in error, but could refer to minor eruptive activity from this relatively youthful-looking volcano. Fumaroles ares located within 600-m-wide Crater B and on its western flank.
