M4.3 Earthquake in the Fiji region — December 2, 2022
2022-12-02 17:46:50 UTC (2022-12-02) · approx. 5:46 AM UTC-12 local
On December 2, 2022 at 17:46 UTC, a magnitude 4.3 deep-focus earthquake struck in the Fiji region, at a depth of 557.9 km and coordinates -20.6854°, -178.4170°.
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.
