Bamus

Stratovolcano · Papua New Guinea · 2248m

Bamus is seen here from the NE beyond the upper slopes of Ulawun. These two volcanoes are the highest in the 1,000-km-long Bismarck volcanic arc. Bamus is covered by rainforest and contains a summit crater filled with a lava dome. A smaller cone is located on the S flank, and a prominent 1.5-km-wide crater with two small adjacent cones is situated halfway up the SE flank.
