On July 9, 2026 at 12:52 UTC, a magnitude 5.1 intermediate depth earthquake struck 59 km NNE of Port-Olry, Vanuatu, at a depth of 160.2 km and coordinates -14.5687°, 167.3264°.0 This earthquake was detected by 46 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
