According to the Papua New Guinea Department of Mining (DOM), reports coming from Bialla Local Level Government (LLG) indicated that Bamus showed signs of unusual activity. At 1010 on 12 July 2006 observers saw white vapor coming out at the summit. The emission was forceful at about 1110 that day, with a tint of gray color in the emission. The vapor-rich plume blew inland to the SSE. No ashfall was reported.

Officials from Bialla LLG together with a DOM observer witnessed the activity, as did Max Benjamin from Walindi Resort (~ 40-50 km away). Benjamin called the Rabaul Volcano Observatory to report the activity. No satellite-detected thermal anomalies at the volcano were reported by the MODIS website for this time frame.

Geologic Background. Symmetrical 2248-m-high Bamus volcano, also referred to locally as the South Son, is located SW of Ulawun volcano, known as the Father. These two volcanoes are the highest in the 1000-km-long Bismarck volcanic arc. The andesitic stratovolcano is draped by rainforest and contains a breached summit crater filled with a lava dome. A satellitic cone is located on the southern flank, and a prominent 1.5-km-wide crater with two small adjacent cones is situated halfway up the SE flank. Young pyroclastic-flow deposits are found on the volcano's flanks, and villagers describe an eruption that took place during the late 19th century.
