Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that during 19-21 and 24-26 March ash plumes from Paluweh rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted 55-335 km SW, WSW, W, NW, and NE.
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.
