Managlase volcanoManaglase volcano is a volcanic field also known as the Managlase Plateau. It is a triangular-shaped area between 460 and 1070 m altitude 35 km SSE of Popondetta in Papua New Guinea, south of the Hydrographers Range and SW of the Dyke Ackland Bay.
The field contains 30 small volcanic centers of late-Pleistocene to Holocene age, including a row of tall cinder cones rising to form the summit at Mount Manna at 1128 m.
The last eruption of Managlase Volcano is unknown, but local stories from villages in the area preserve the memory of activity from the Kururui cinder cone and a nearby explosion crater.
Background:The fault-bounded plateau contains trachybasaltic lava cones and flows, scoria mounds, cinder cones, and explosion vents of the Uoivi Volcanics. On its eastern side it is capped by rhyodacitic ash cones, lava domes, and ashflow deposits of the Manna Volcanics.
