2026-09-05 23:46:26 UTC (2 hours ago) · approx. 10:46 AM UTC+11 local
On September 5, 2026 at 23:46 UTC, a magnitude 4.6 intermediate depth earthquake struck 71 km N of Isangel, Vanuatu, at a depth of 240.4 km and coordinates -18.8949°, 169.2507°. This earthquake was detected by 44 seismic stations with excellent 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.
