Photo Gallery

The small, 1.4 x 1.7 Boisa Island is seen here in the foreground from the west with steaming Manam volcano in the distance. Boisa volcano consists of a large cone with a summit crater open to the north whose rim extends to the east coast. The crater of the topographically indistinct stratovolcano is filled by two steep-sided lava domes, the largest of which (left) forms the 240-m high point of the island. No historical eruptions have been observed from Boisa, in contrast to Manam, which is one of Papua New Guinea's most active volcanoes.
