On May 11, 2025 at 17:38 UTC, a magnitude 4.6 shallow crustal earthquake struck 27 km W of Port-Vila, Vanuatu, at a depth of 37.6 km and coordinates -17.7132°, 168.0571°. This earthquake was detected by 32 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
