Ulawun volcano (Papua New Guinea): ash cloud from yesterday's major explosion dissipated, but SO2 plume over area

No new significant ash emissions have been observed from the volcano today, but satellite images show strong heat and intense steaming from the summit crater.
As well, fresh deposits of pyroclastic flows from yesterday's eruption can be recognized on satellite imagery.
It seems that these flows fortunately did not reach great distance beyond the base of the steeper summit cone. There are no reports of significant damage, partly this could be because most of the local residents near the volcano are still in evacuation centers.
Although no ash is visible on satellite data, VAAC Darwin continues to warn that some remaining ash plume could be drifting in up to 45,000 ft altitude towards the SW, but suggests that the concentration of residual volcanic ash is by now very low. The latest VVAC report expected that the ash is likely to have dissipated by now or will disappear within a few hours.
In contrast, a large SO2 plume from the eruption continues to be drifting and expanding over the area (SO2 aerosols stay suspended much longer in the atmosphere)...
