Managlase Plateau
"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 dotted 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 on the Managlase Plateau is not known, but the trachybasaltic Kururui cinder cone and a nearby explosion crater were active within memory of nearby villagers (Ruxton, 1966)."  -Smithsonian Volcano Archive
