Pyroclastic flow at SInabung yesterday 11:45 local time (photo: Mbah Lëwå / facebook)Bagana (Bougainville Island, Papua New Guinea): Ash emissions have been stronger over the past days, suggesting that activity has picked up.
Darwin VAAC reported an ash plume extending 40 nautical miles to the NE this morning.
Sinabung (Sumatra, Indonesia): The volcano continues to extrude viscous lava, feeding the lava dome occupying the summit crater and a new lava lobe on the upper eastern flank.
Collapses from this lobe and the dome have been producing frequent smaller to medium-sized pyroclastic flows on the eastern and sometimes northeastern flank. A moderately large pyroclastic flow yesterday at 11:45 local time reached approx. 3.5 km and produced an ash plume that rose to approx. 4 km altitude.
Since 26 March, lava has also been overflowing from the dome onto the northeastern flank, which is why pyroclastic flows have now also been affecting this sector.
Dukono (Halmahera): Activity at the volcano remains elevated. VAAC Darwin frequently reports ash plumes drifting NE at 2-3 km altitude visible on satellite images.
