Seismic activity from Paluweh (also known as Rokatenda) increased during 12-18 January, prompting CVGHM to raise the Alert Level from 1 to 2 (on a scale of 1-4) on 19 January. Fog prevented visual observations of the volcano.
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.
