On December 28, 2023 at 16:46 UTC, a magnitude 4.4 deep-focus earthquake struck 205 km ENE of Levuka, Fiji, at a depth of 535.0 km and coordinates -17.3200°, -178.9095°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
