On July 27, 2024 at 20:34 UTC, a magnitude 4.3 deep-focus earthquake struck south of the Fiji Islands, at a depth of 526.1 km and coordinates -23.9869°, 179.8898°.

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.
