The rock at the centre of the tall domes in these islands was thus recently very deep in the Earth. Over a very short time, geologically speaking, these packets of rocks have ascended through the Earth's shallow mantle and pushed through the crust to form the gneiss domes we find today – the vestiges

These islands are thought to be geophysically significant because they lie immediately ahead of the westernmost rift tip of the
Woodlark spreading centre, which has been propagating westwards into the continent. The D'Entrecasteaux thus represent a stage of continental breakup just preceding

fields. Fergusson Island has three volcanic masses over 1,828 m (5,997 ft) high. There are geothermal areas in the south east area of
Goodenough Island and the Bwabwadana and Iamalele on Fergusson Island. A particularly active hot springs is located at Deidei on Fergusson.

It was used by allied forces from June 1943 to August 1944 as a staging point for operations in New Guinea and nearby occupied islands. Vivigani airstrip has been open to commercial service since 1963. A US Navy PT-Boat base was established on
Fergusson Island in June 1942.
