On July 4, 2026 at 22:26 UTC, a magnitude 4.4 deep-focus earthquake struck in the Fiji region, at a depth of 623.1 km and coordinates -21.1830°, -179.2129°.

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.
