Managlase Plateau

火山原 · Papua New Guinea · 1342m

Thirty small volcanic centers have been identified in the Managlase Plateau in SE Papua New Guinea. Some of these are shown in this July 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 13 km across). Several vegetated craters, lava domes, and cones are visible across this image, and lava flows have also been reported.

地質学的概要

Thirty small volcanic centers of late-Pleistocene to Holocene age are located in SE Papua New Guinea on the Managlase Plateau, south of the Hydrographers Range and SW of the Dyke Ackland Bay. The fault-bounded plateau forms a triangular-shaped area with trachybasaltic lava cones and flows, scoria mounds, cinder cones, and explosion vents of the Uoivi Volcanics, and capped on its eastern side by rhyodacitic ash cones, lava domes, and ashflow deposits of the Manna Volcanics. The date of the most recent eruption is not known, but the trachybasaltic Kururui cinder cone and a nearby explosion crater were active within memory of nearby residents (Ruxton, 1966).
