Mt Lamington volcano is a large andesitic stratovolcano within sight of the provincial capital Popondetta north of the Owen Stanley Range. It rises 1680 m above the coastal plain.
The forested Mount Lamington had not been known as a volcano, before it erupted violently in 1951 and caused one of the 20th century's worst volcanic desasters, killing more than 3000 people.
Mount Lamington is one of 4 large Quaternary stratovolcanoes on the north coast of southeastern New Guinea. The other 3 volcanoes are Hydrographers Range, Mount Trafalgar, and Mount Victory volcanoes.
