2025-07-10 23:58:29 UTC (2025-07-10) · approx. 11:58 AM UTC-12 local
On July 10, 2025 at 23:58 UTC, a magnitude 4.4 shallow crustal earthquake struck 124 km SE of Hihifo, Tonga, at a depth of 36.4 km and coordinates -16.8066°, -173.0344°.
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.
