Indonesian Meteorological Institute personnel reported that Paluweh has erupted for the second time this year. The meteorology bureau on Flores Island . . . said it recorded 809 "strong tremors" 17-22 August. "Lava and burning rocks" were repeatedly erupted on 22 August. On 24 August the bureau recorded ocean water temperatures as high as [98°C] around the island. No casualties were reported, but inhabitants evacuated the area. Crops and fishing boats were damaged.

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.
