#RedAlert #MajorEruption – Major #AshClouds Drifting East And South From #UlawunVolcano In #PapuaNewGuinea
While it is not only night over Papua New Guinea now, a vast area around the volcano is now likely to be shredded in darkness caused by ash from the eruption.
It is unclear whether the activity at the volcano still continues or has subsided or ended. However, the ash plume has been split in two major portions by winds blowing in different directions at different altitudes:
– the highest portion at 63,000 ft (20 km, flight level 630) is rapidly drifting east and already at more than 500 km distance from the volcano.
– the “lower” part of the plume, up to 55,000 ft (17 km, flight level 550) altitude is instead spreading and drifting more slowly to the south.
The aviation color code is red and all aircraft should avoid the affected areas in a wide distance
