| The small 2.4 x 1.6 km island of Bam is the summit of a mostly submerged volcano that is one of the more active in Papua New Guinea. Bam is the SE-most of the Schouten Islands, and lies off the coast of New Guinea, about 40 km NNE of the mouth of the Sepik River. A steep-walled summit crater that is 300 m wide and 180 m deep is the source of Bam's recent eruptions, which have kept the upper half of the cone sparsely vegetated. A NE-trending landslide scarp extends across the upper part of the andesitic volcano from the SW coast, and a large submarine debris-avalanche deposits lies to the south and SW. The younger summit cone partially buries the eastern side of the collapse scarp. A recent lava platform on the north flank supports the small island's only villages. Historical eruptions, recorded since 1872, have been restricted to small-to-moderate explosive activity from the summit crater. | |||
