Paluweh volcano (also known as Rokatenda), is the tip of a large, mostly submerged stratovolcano rising 3000 m from the sea floor. It forms a small 8 km wide island with the same name north of Flores Island. Paluweh has a complex summit composed of several overlapping craters and lava domes up to 900 m wide. Several flank vents were formed by flank eruptions on a NW-trending fissure. The largest historical eruption of Paluweh in 1928 was highly explosive and produced a landslide triggering a tsumani.
