On July 1, 2025 at 23:55 UTC, a magnitude 4.2 deep-focus earthquake struck 270 km E of Levuka, Fiji, at a depth of 559.0 km and coordinates -18.2724°, -178.1364°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
