2026-07-12 10:10:02 UTC (1 hour ago) · approx. 10:10 PM UTC-12 local
On July 12, 2026 at 10:10 UTC, a magnitude 4.2 deep-focus earthquake struck in the Fiji region, at a depth of 571.9 km and coordinates -20.7542°, -178.3336°.
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.
