On December 14, 2024 at 19:22 UTC, a magnitude 3.9 deep-focus earthquake struck 298 km ESE of Levuka, Fiji, at a depth of 523.2 km and coordinates -18.9210°, -178.0065°.

Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
