Ulawun, Papua New Guinea

RVO reported that increased seismic activity at Ulawun began on 7 June. During 18 June-2 July, mostly moderate-to-strong emissions of white vapor produced plumes that rose from Ulawun and seismometers recorded high-frequency earthquakes. On 22 June, noises heard in villages to the NE accompanied some of the earthquakes. On 28 June, an Intensity II earthquake was felt in areas nearby and accompanied by a booming noise. A team of officers from RVO and West New Britain Provincial Disaster Office informed communities on the activity status of Ulawun. On 30 June, RVO reported that the level of Alert at Ulawun was at “Stage 2”, or that there was an increase in seismic activity above background level. During 1-2 July, roaring and jet noises were reported from people to the NE.
