Isla Goodenough

Goodenough

Campo volcánico · Papua New Guinea · 220 m

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).

Resumen geológico

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.

Resumen de Wikipedia

La isla Goodenough es una isla en el mar de Salomón, que es la más occidental de las tres grandes islas del grupo D'Entrecasteaux, en la provincia Milne Bay de Papua Nueva Guinea. Se encuentra al este del territorio continental de Nueva Guinea y al suroeste de las islas Trobriand. No se debe confundir con la isla de Goodenough. Es más o menos de forma circular, mide 39 por 26 kilómetros con una superficie de 687 kilómetros cuadrados y una costa o litoral de 116 kilómetros. Posee una franja costera de ancho variable de entre 2 hasta 10 kilómetros. La isla se eleva abruptamente hasta la cumbre del monte Vineuo, que alcanza los 2.536 metros sobre el nivel del mar, convirtiéndola en una de las islas más precipitadas en el mundo.
