On August 16, 2022 at 19:56 UTC, a magnitude 4.1 intermediate depth earthquake struck 40 km ESE of Port-Vila, Vanuatu, at a depth of 140.0 km and coordinates -17.9134°, 168.6437°.
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.
