Rabaul, Papua New Guinea

RVO reported that during 3-6 November ash plumes from Rabaul caldera’s Tavurvur cone rose to altitudes of 1.7-2.2 km (5,600-7,200 ft) a.s.l. and drifted NW. Ashfall was reported in areas downwind. Sub-continuous incandescence from the vent was observed, and rumbling and roaring noises were reported on some days. Explosions or forceful emissions sometimes ejected incandescent lava fragments.

Based on analysis of satellite imagery, the Darwin VAAC reported that during 7 and 9-12 November ash plumes rose to an altitude of 2.4 km (8,000 ft) a.s.l. and drifted N and NW.
