On August 3, 2022 at 17:24 UTC, a magnitude 4.1 deep-focus earthquake struck in the Fiji region, at a depth of 599.1 km and coordinates -20.6771°, -178.6765°.

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.
