On April 3, 2025 at 13:58 UTC, a magnitude 4.8 shallow crustal earthquake struck 22 km W of Port-Vila, Vanuatu, at a depth of 33.7 km and coordinates -17.7114°, 168.1013°. This earthquake was detected by 68 seismic stations with good location accuracy and was assigned a USGS significance rating of 358, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
