On March 19, 2024 at 22:43 UTC, a magnitude 4.2 intermediate depth earthquake struck 162 km WNW of Fangale’ounga, Tonga, at a depth of 216.3 km and coordinates -19.0814°, -175.6990°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
