2026-02-25 17:12:18 UTC (2026-02-25) · approx. 4:12 AM UTC+11 local
On February 25, 2026 at 17:12 UTC, a magnitude 4.9 intermediate depth earthquake struck 69 km NNE of Isangel, Vanuatu, at a depth of 250.1 km and coordinates -18.9230°, 169.4120°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
