Goodenough (center) is the roughly circular volcanic island that is the westernmost of the D'Entrecasteaux Islands in this NASA satellite image with north to the upper right. Several Holocene eruptive centers that may be only a few hundred years old are located around the margins of fault-bounded metamorphic rocks that form the central part of Goodenough Island. The youngest volcanic features, which include the Walilagi Cones, are located at the SE end of the island on the Bwaido Peninsula (lower center).

Sintesi geologica

Goodenough is a roughly circular volcanic island that is the westernmost of the D'Entrecasteaux Islands off the NE tip of Papua New Guinea. Several basaltic andesite and andesitic Holocene eruptive centers are located around the margins of fault-bounded metamorphic rocks that form the central part the island. The youngest volcanic features, which include the Walilagi Cones, are located at the SE end of the island. These well-developed ash cones and blocky lava flows on the N and E flanks of the Bwaido Peninsula may have erupted within the past few hundred years.

Riassunto in inglese

Goodenough Island in the Solomon Sea, also known as Nidula Island, is the westernmost of the three large islands of the D'Entrecasteaux Islands in Milne Bay Province of Papua New Guinea. It lies to the east of mainland New Guinea and southwest of the Trobriand Islands. It is roughly circular in shape, measuring 39 by 26 kilometres with an area of 687 square kilometres (265 sq mi) and a shoreline of 116 kilometres (72 mi). A coastal belt varying in width from 2 to 10 kilometres is covered in grasslands and dissected by streams and coastal swamps. The island rises sharply to the summit of Mount Vineuo, 2,536 metres (8,320 ft) above sea level, making it one of the most precipitous islands in the world. The small outlier Wagifa Island lies to the south-east of the island, and is included within Goodenough's administration.
