Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that on 29 January ash plumes from Paluweh rose to an altitude of 1.8 km (6,000 ft) a.s.l. and drifted less than 20 km ENE.

Geologic Background. Paluweh volcano, also known as Rokatenda, forms the 8-km-wide island of Palu'e north of the volcanic arc that cuts across Flores Island. The broad irregular summit region contains overlapping craters up to 900 m wide and several lava domes. Several flank vents occur along a NW-trending fissure. The largest historical eruption occurred in 1928, when strong explosive activity was accompanied by landslide-induced tsunamis and lava dome emplacement. Pyroclastic flows in August 2013 resulted in fatalities.
