2026-01-31 20:08:32 UTC (2026-01-31) · approx. 8:08 AM UTC+12 local
On January 31, 2026 at 20:08 UTC, a magnitude 4.4 deep-focus earthquake struck south of the Fiji Islands, at a depth of 493.5 km and coordinates -24.9177°, 179.8340°.
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.
