Paluweh

Stratovulcano · Indonesia · 875 m

An unvegetated lava dome is visible at the summit of Paluweh. The massif forms an 8-km-wide island located N of the volcanic arc that includes Flores Island. The summit region contains overlapping craters and lava domes, and several flank vents occur along a NW-trend. Multiple eruptions have occurred through historical time.

Sintesi geologica

Paluweh, 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. A large eruption in 1928 included strong explosive activity accompanied by landslide-induced tsunamis and lava dome emplacement. Pyroclastic flows in August 2013 resulted in fatalities.
