Bamus

Stratovulcano · Papua New Guinea · 2248 m

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.

Sintesi geologica

Symmetrical Bamus volcano, also referred to locally as the South Son, is located SW of Ulawun volcano, known as the Father. The andesitic stratovolcano is covered in rainforest and contains a breached summit crater filled with a lava dome. There is a cone on the southern flank, and a prominent 1.5-km-wide crater with two small adjacent cones halfway up the SE flank. Young pyroclastic-flow deposits are found on the flanks, and residents describe an eruption that took place during the late 19th century.
