  • Following the Mount Ulawun eruption on 1 October, the volcanic explosion activity continues, the ash plume rose 6,100 m altitude and is moving in south-west direction at 37 km/h. 
  • The eruption has forced the evacuation of several people who recently returned to their homes, following a previous eruption and evacuation. 
  • As of 10.00 a.m. local time 2 October, the eruption of Ulawun continues via a new vent, low on its south-west flank. The alert level remains at stage 3, indicating a high threat to life. Seismicity remains high with tremors of similar intensity or slightly above. If the eruption continues, or the lava effusion rate increases, areas to the north-west of the current vent may be affected. Ash can be expected in down-wind areas. 
PNG – Volcanic activity, Ulawun, West New Britain and East New Britain provinces (ECHO 01 Oct 2019)Tue, 01 Oct 2019 04:00

  • Ulawun erupted at about 5: 00 a.m. local time (UTC+10) on 1 October, following a swarm of seismic activity that began around 11:30 a.m. local time on 30 September.
  • The eruption was visible from red incandescent glow shooting up less than 100m from the base and an ash plume rising less than 1,000 metres. Preliminary observations suggest areas in the westerly direction may be affected by ashfall, but the current level of exposure to ashfall remains low. The West New Britain Provincial Disaster Centre reported that 6 care centres are open for evacuating residents. As of two weeks ago, approximately 6,200 people were staying in the care centres, which had remained open since the previous eruptions.

  • Between3,000 and 5,000 people voluntarily evacuated the immediate vicinity of Ulawun, according to the National Disaster Centre. 
  • The ash plume is moving generally south but has slowed in recent hours. Air Niugini has cancelled flights to Hoskins Airport until further assessments are made. 
  • The cluster system is to be activated in response to food, water, shelter and non food item needs among the evacuees. As the area has been cut off from the highway, relief items will be transported by road from Kimbe to Bialla, and then via helicopter to those affected.
