On March 12, 2022 at 21:47 UTC, a magnitude 4.4 intermediate depth earthquake struck near Vanuatu, at a depth of 267.1 km and coordinates -15.8943°, 168.3303°.

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.
