On December 27, 2025 at 21:49 UTC, a magnitude 4.1 deep-focus earthquake struck 206 km ENE of Levuka, Fiji, at a depth of 550.0 km and coordinates -17.4676°, -178.8382°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
