In 2003, Geoazur Joint Research Unit applied to GIS-RAP to set up five accelerometric stations, namely three in New Caledonia and two on Futuna Island. All five stations were set up from mid-April 2006, .starting with New Caledonia. The New Caledonian RAP (French permanent accelerometric network) is currently a regional network within the national RAP network.

New Caledonia in the Southwest Pacific is located in one of the globe’s most active areas on the edge of the Australian Plate, which is subducting beneath the Pacific Plate. Convergence velocities along the active zone (New Hebrides Trench) vary from 5 cm/year in the North (Santo) to 12 cm/year in the South (Tanna). Earthquake characteristics and recurrence: as displayed by the region’s historical seismicity map, earthquakes occurring ahead of the arc are relatively superficial (> 70 km) and it is believed that an earthquake of magnitude ≥ 7.0 occurs once or twice a year.


The New Caledonian seismic network is made up of seven seismic stations spread across the Territory, particularly in seismically active areas, i.e. the southern mainland and Loyalty Islands.
