Why does Vanuatu experience frequent earthquakes?

Vanuatu experiences frequent earthquakes because it is located within the Ring of Fire, the world's most seismically active belt. The country is situated along a convergent plate boundary where tectonic plates interact, leading to significant structural instability.1

Specifically, the islands are part of an island arc system associated with the subduction of the Coral Sea floor beneath the region. This process is marked by the New Hebrides Trench, a deep-sea feature that reflects the intense tectonic activity in the area. The stresses generated by the compression of these tectonic plates create the seismic activity that results in frequent earthquakes.231
