The small 2.4 x 1.6 km island of Bam, seen here from the south, is the summit of a mostly submerged volcano that is one of the more active in Papua New Guinea. 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 younger cone (center horizon) formed inside a SE-facing landslide scarp. Historical eruptions, recorded since 1872, involved small-to-moderate explosive activity from the summit crater.

The small island with the irregular shoreline at the upper left is Blup Blup. This 3.5-km-wide forested island contains lava flows with well-defined flow fronts, and a weak thermal area is located on the west coast. No historical eruptions have occurred, but the volcano may have been active during the Holocene. Blup Blup is part of the Schouten Islands, along with Kadovar volcano (the small circular island to the south, above the prominent sediment plume at the lower left) and Bam volcano (right).
