On March 30, 2024 at 21:33 UTC, a magnitude 4.4 shallow crustal earthquake struck 184 km W of Pangai, Tonga, at a depth of 8.8 km and coordinates -19.5041°, -176.0797°.
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.
