On October 28, 2026 at 02:21 UTC, a magnitude 6.0 shallow crustal earthquake struck 214 km NW of Port-Olry, Vanuatu, at a depth of 10.0 km and coordinates -13.9312°, 165.4460°.0 The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 37 seismic stations with good location accuracy and was assigned a USGS significance rating of 554, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 6.0 releases seismic energy equivalent to roughly 15 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 8.3 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.
