RVO reported that ash plumes from Rabaul caldera’s Tavurvur cone continued to be emitted during 29-31 August. The plumes drifted NW and caused ashfall in areas downwind. Continuous incandescence at the summit was observed and roaring noises were heard. Explosions also ejected incandescent lava fragments.
