On June 29, 2024 at 16:44 UTC, a magnitude 4.1 deep-focus earthquake struck in the Fiji region, at a depth of 394.4 km and coordinates -17.0068°, -177.5455°.

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.
