The Darwin VAAC reported that a large thermal anomaly over Manam was identified in satellite images during 21-22 December. A discrete ash plume rose to 3.4 km (11,000 ft) a.s.l. and drifted SE on 21 December.
Ash plumes may have risen to 10.7 km (35,000 ft) a.s.l. during 0137-0300 on 22 December, though weather clouds and heavy rain obscured satellite views; the plumes were unconfirmed by ground observers. At 1200 on 22 December an ash plume rose to 4.9 km (16,000 ft) a.s.l., drifted E, and dissipated within four hours.
