Hydrographers Range

Tipo
Stratovulcano
Altitudine
1915 m
Ultima eruzione
Sconosciuto
The Hydrographers Range, seen here from the W, is a forested, deeply dissected volcanic massif extending from the E margin of Mount Lamington (lower right) to the northern coast of Papua New Guinea. Most activity took place during the Pleistocene, but well-preserved scoria cones and craters suggest that some Holocene activity occurred. This 1947 photo was taken prior to Lamington's catastrophic eruption in 1951.

Sintesi geologica

The Hydrographers Range is a forested, deeply dissected andesitic volcanic massif extending from the eastern margin of Mount Lamington north to the coast of eastern Papua New Guinea. Most activity took place during the Pleistocene, but perfectly preserved cinder cones and explosion craters on the southern side of the range suggested that some activity took place during the Holocene (Taylor, 1958). Other well-preserved cones are situated in the high country overlooking Songade village on the coast.
