Where is volcano Manam?
mainland Papua New Guinea
Manam is located 13 km off the N coast of mainland Papua New Guinea and has had eruptions documented since 1616. It contains two active summit craters, Main and South, which have been characterized by occasional Strombolian activity, lava flows, pyroclastic avalanches, and ash plumes.
