On June 26, 2026 at 17:09 UTC, a magnitude 4.6 shallow crustal earthquake struck 165 km SW of Port-Vila, Vanuatu, at a depth of 10.0 km and coordinates -18.9529°, 167.4029°. This earthquake was detected by 25 seismic stations with good 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.
