The zone includes most of the islands of Vanuatu, the Santa Cruz islands of the southern Solomon Islands, [4] and the Loyalty Islands.A number of ocean floor features are related to the zone, in particular the New Hebrides Trench (South New Hebridies Trench) [5] and the North New Hebrides Trench (Torres Trench) which is separated from the southern trench by the d'Entrecasteaux Ridge and the ...
The area of the southern part of the subduction zone between the latitudes 21.5 and 22.5° S and the longitudes 169 and 170° E is very active. [5] There have been multiple earthquakes including swarms of magnitude Mw 7.0+ during recent decades impacting on New Caledonia and Vanuatu. [5]
This subduction zone is one of the most active plate boundaries globally, moving at a rate of approximately 170 mm (7 in) per year. [5] While much of the island arc experiences intermediate-depth earthquakes along a Wadati–Benioff zone that dips steeply at 70°, the area adjacent to the D'entrecasteaux Ridge does not. There is a corresponding ...
Volcanic activity is also present along this north-northwest trending and northeast-dipping subduction zone. [2] While much of the island arc experiences intermediate-depth earthquakes along a Wadati–Benioff zone that dips steeply at 70°, the area adjacent to the d'Entrecasteaux Ridge does not. There is a corresponding gap in seismicity that ...
PORT VILA, Vanuatu (AP) -- Relief workers saw a flattened landscape and widespread destruction in Vanuatu's outer islands Tuesday after struggling for days to reach the areas of the South Pacific ...
The d'Entrecasteaux (French pronunciation: [dɑ̃tʁəkasto]) Ridge (DER) is a double oceanic ridge in the south-west Pacific Ocean, north of New Caledonia and west of Vanuatu Islands. It forms the northern extension of the New Caledonia– Loyalty Islands arc , and is now actively subducting in the Vanuatu subduction zone under the Vanuatu/New ...
