RVO reported that white vapor emissions from the Bagiai cone in Karkar’s inner caldera were observed by a visiting field team during 27-31 December. The resultant white vapor plume was also visible from the mainland. Communities to the W and SW reported hearing roaring noises associated with gas emissions. Images sent to RVO on 11 December indicated that the vegetation on the SE flank was completely withered.
