On December 13, 2024 at 20:03 UTC, a magnitude 4.3 shallow crustal earthquake struck 98 km N of Hihifo, Tonga, at a depth of 46.1 km and coordinates -15.0699°, -173.8549°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
