Felt by 5 people across nearby locations.
On December 17, 2025 at 22:30 UTC, a magnitude 5.0 intermediate depth earthquake struck 82 km SSE of Port-Vila, Vanuatu, at a depth of 95.8 km and coordinates -18.4434°, 168.5671°. This earthquake was detected by 46 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 386, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Vanuatu, a region characterized by the New Hebrides subduction zone, where the Australian Plate subducts eastward at approximately 90 mm per year. View all earthquakes in Vanuatu.
