On January 31, 2022 at 19:47 UTC, a magnitude 4.4 intermediate depth earthquake struck 101 km E of Lakatoro, Vanuatu, at a depth of 187.4 km and coordinates -16.2127°, 168.3546°.
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.
