Mount Lamington’s 1951 eruption caused one of Papua New Guinea’s deadliest volcanic disasters.
Mount Lamington is a heavily forested stratovolcano in Oro Province, Papua New Guinea. Before January 1951, it was not widely recognized as an active volcano. Its sudden explosive eruption produced pyroclastic flows that devastated surrounding communities and killed about 3,000 people.
The disaster became especially important in volcanology because it demonstrated how dangerous apparently quiet volcanoes can be. Scientists later studied the eruption in detail, improving understanding of pyroclastic flows and volcanic hazard assessment.
Mount Lamington is sometimes confused with Tavurvur or Ulawun, other famous Papua New Guinean volcanoes. Those volcanoes have different eruption histories and locations. Lamington’s defining fact is the catastrophic 1951 eruption and its severe impact on Oro Province.
