On February 7, 2025 at 18:58 UTC, a magnitude 4.0 deep-focus earthquake struck 274 km NW of Houma, Tonga, at a depth of 574.9 km and coordinates -19.4300°, -177.1735°.
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.
