On March 30, 2024 at 23:08 UTC, a magnitude 4.1 intermediate depth earthquake struck 167 km WSW of Hihifo, Tonga, at a depth of 252.6 km and coordinates -16.7867°, -175.1078°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
