- VolcanoBalbi 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.
