On November 9, 2022 at 18:47 UTC, a magnitude 4.3 shallow crustal earthquake struck 117 km SSW of Kokopo, Papua New Guinea, at a depth of 53.3 km and coordinates -5.3419°, 151.8965°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
