On January 17, 2022 at 19:51 UTC, a magnitude 4.2 intermediate depth earthquake struck 55 km E of Lakatoro, Vanuatu, at a depth of 175.7 km and coordinates -16.0084°, 167.9298°.

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.
