1951 Eruption Of Mount Lamington
In early January 1951, a series of minor explosions and earthquakes rocked Mount Lamington, a volcano in Oro Province, Territory of Papua and New Guinea. Prior to the eruption, Mount Lamington was not recognized as a volcano due to the absence of historically-recorded eruptions and dense vegetation cover. From January 15, volcanic activity intensified, and tall eruption plumes were generated. The largest eruption occurred on the morning of January 21 when a thick black plume of ash rose into the atmosphere. The eruption collapsed a lava dome and produced a lethal pyroclastic flow that killed 2,942–3,466 people. In the years after the eruption, new lava domes formed and collapsed in succession. Activity persisted until July 1956. The eruption is the deadliest natural disaster in Australian history, as the region was under the rule of the Government of Australia.

Mount Lamington
Mount Lamington is an andesitic stratovolcano in the Oro Province of Papua New Guinea. The forested peak of the volcano had not been recognised as such until its devastating eruption in 1951 that caused about 3,000 deaths. The volcano rises to 1680 meters 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. The mountain was named after Charles Cochrane-Baillie, 2nd Baron Lamington who was Governor of Queensland. 1951 eruption Mount Lamington began to erupt on the night of January 18, 1951. Three days later there was a violent eruption when a large part of the northern side of the mountain was blown away and devastating pyroclastic flows poured from the gap for a considerable time afterwards. The area of extreme damage extended over a radius ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
