Lamington Volcano, Papua New Guinea

Mount Lamington, seen here in eruption from the north in late 1951, is an andesitic stratovolcano with a 1.3-km-wide breached summit crater containing a lava dome.

Prior to its renowned devastating eruption in 1951, the forested peak had not been recognized as a volcano.

The catastrophic 1951 eruption produced devastating pyroclastic flows and surges that swept all sides of the volcano, killing nearly 3000 persons.

The eruption concluded with growth of a 560-m-high lava dome in the summit crater.

Lamington is an andesitic stratovolcano with a 1.3-km-wide breached summit crater containing a lava dome.

Prior to its renowned devastating eruption in 1951, the forested peak had not been recognized as a volcano.

Mount Lamington rises to 1680 m above the coastal plain north of the Owen Stanley Range.

A summit complex of lava domes and crater remnants rises above a low-angle base of volcaniclastic deposits that are dissected by radial valleys.

A prominent broad "avalanche valley" extends northward from the breached crater.

Ash layers from two early Holocene eruptions at Lamington have been identified.

After a long quiescent period, the volcano sprang suddenly to life in 1951, producing a powerful explosive eruption during which devastating pyroclastic flows and surges swept all sides of the volcano, killing nearly 3000 persons.

The eruption concluded with growth of a 560-m-high lava dome in the summit crater.
