The significance index is 500 (on a scale that runs through 1 000), based on magnitude and estimated impact.
Vanuatu lies along the boundary between the Australian and Pacific tectonic plates, a region known for high seismic activity due to frequent interactions, including subduction and strike-slip faulting.
