2024-12-15 22:09:31 UTC (2024-12-15) · approx. 10:09 AM UTC-12 local
On December 15, 2024 at 22:09 UTC, a magnitude 4.3 deep-focus earthquake struck south of the Fiji Islands, at a depth of 491.4 km and coordinates -23.9699°, -179.9374°.
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.
