Bagana, Papua New Guinea

RVO reported that during 18 October-10 December white vapor plumes from Bagana were occasionally accompanied by ash plumes generated by rockfalls from the edges of the lava flow on the SE flank. Occasionally, booming and roaring noises were heard and incandescence at the summit was observed. Two explosions were accompanied by ash plumes on 19 and 27 November. Incandescent lava fragments were ejected from the summit on 7 and 9 December. On 9 December, an ash plume rose to an altitude of 2.8 km (9,200 ft) a.s.l. A lava flow became active and was continuously incandescent down the SE flank.
