The base of the plume was often reddish during 29 November-5 December reflecting incandescence from lava in the crater.Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG, also known as CVGHM); Badan Nacional Penanggulangan Bencana (BNPB) PVMBG reported that during 13-19 December gray-and-white plumes rose as high as 2.5 km above Agung’s crater rim and drifted W, N, and E; weather clouds and fog sometimes prevented visual observations.BNPB posted two map-view images of Agung, one from 20 October showing pre-eruptive conditions and one from 16 December showing the lava that had erupted onto the crater floor, noting that about 1/3 of the crater had been filled with an estimated 20 million cubic meters of lava.Crater incandescence was observed at 2100, signifying the presence of lava in the crater.BNPB noted that the number of evacuees was 25,016 (spread out in 224 shelters) On 26 November dark gray ash plumes rose 2 km at 0505, 3 km at 0545, and 4 km at 0620, and drifted E and SE.
