2026-09-01 18:37:29 UTC (54 min ago) · approx. 5:37 AM UTC+11 local
On September 1, 2026 at 18:37 UTC, a magnitude 5.0 intermediate depth earthquake struck 118 km SSE of Isangel, Vanuatu, at a depth of 122.5 km and coordinates -20.5024°, 169.7829°. This earthquake was detected by 79 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
