Ulawun volcano (New Britain, Papua New Guinea) - Smithsonian / USGS Weekly Volcanic Activity Report for 2 October-8 October 2019 (New Activity / Unrest)
RVO reported that the fissure eruption on Ulawun's WSW flank had ceased by 4 October, producing only diffuse white-to-gray steam plumes with a blueish tinge from the main coalesced vent. Weak incandescence from the vent was visible at night on 5 October. The lava-flow rate slowed to 3-5 m a day, likely because it was no longer being fed.
