Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that on 6 and 8 December ash plumes from Paluweh rose to an altitude of 3.7 km (12,000 ft) a.s.l. and drifted 35-75 km NW, W, and SW.
Geological Summary. 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.
