M4.3 Earthquake in the Fiji region — November 24, 2025
2025-11-24 22:45:42 UTC (2025-11-24) · approx. 10:45 AM UTC-12 local
On November 24, 2025 at 22:45 UTC, a magnitude 4.3 deep-focus earthquake struck in the Fiji region, at a depth of 620.0 km and coordinates -18.7664°, -177.6790°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
