All times are local (unless otherwise noted)
PVMBG reported that observers at a post located in Kampung Ropa, Keliwumbu Village, noted that during 3-17 November diffuse white plumes rose as high as 75 m above Paluweh. Seismicity remained relatively stable, and was characterized by shallow and deep volcanic earthquakes, and signals indicating emissions and avalanches. The Alert Level remained at 2 (on a scale of 1-4). Residents and tourists were reminded not to approach the summit within a radius of 1.5 km.
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.
