M4.0 Earthquake in the Fiji region — June 25, 2026
2026-06-25 19:26:06 UTC (2026-06-25) · approx. 7:26 AM UTC-12 local
On June 25, 2026 at 19:26 UTC, a magnitude 4.0 deep-focus earthquake struck in the Fiji region, at a depth of 642.0 km and coordinates -21.0426°, -179.0714°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
