Rabaul, Papua New Guinea

RVO reported that during 7-12 October steam and ash plumes from Rabaul caldera’s Tavurvur cone rose to an altitude of 2.7 km (8,900 ft) a.s.l. and drifted N, NW, and W. During 11-12 October, ash emissions increased in frequency; ashfall was reported in areas downwind, including Namanula Hill (3 km W). Continuous incandescence from the vent was observed. Loud roaring noises were reported on 9 October.

Based on analysis of satellite imagery and information from RVO, the Darwin VAAC reported that during 13-14 October ash plumes rose to an altitude of 2.4 km (8,000 ft) a.s.l. and drifted NW and WNW.
