2026-01-01 21:35:02 UTC (2026-01-01) · approx. 8:35 AM UTC+11 local
On January 1, 2026 at 21:35 UTC, a magnitude 5.2 intermediate depth earthquake struck 111 km SSE of Port-Vila, Vanuatu, at a depth of 139.1 km and coordinates -18.6924°, 168.6565°. This earthquake was detected by 42 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
