On May 22, 2021 at 22:18 UTC, a magnitude 4.2 intermediate depth earthquake struck 53 km ENE of Port-Olry, Vanuatu, at a depth of 136.9 km and coordinates -14.7997°, 167.5026°.
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.
