Bouganville Island is geographically part of the Solomon Islands chain to the east of Papua New Guinea. (Politically, the island is part of Papua New Guinea.) Bouganville is typical of many Pacific Rim islands in that volcanism has played a large part in both its geological and recorded history. The island hosts three large volcanoes along its northwest-southeast trending axis: Mount Balbi, Mount Bagana, and the Mount Takuan volcanic complex. Mount Bagana, located near image center in this astronaut photograph, is the only historically active volcano on the island.
