On December 3, 2021 at 17:12 UTC, a magnitude 4.1 deep-focus earthquake struck 284 km E of Sola, Vanuatu, at a depth of 617.3 km and coordinates -13.9337°, 170.1819°.
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.
