Felt by 19 people across nearby locations.
On July 13, 2025 at 06:16 UTC, a magnitude 5.3 shallow crustal earthquake struck 44 km S of Port-Vila, Vanuatu, at a depth of 32.4 km and coordinates -18.1332°, 168.3777°. This earthquake was detected by 65 seismic stations with good location accuracy and was assigned a USGS significance rating of 441, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
