On February 22, 2025 at 23:07 UTC, a magnitude 4.0 intermediate depth earthquake struck 94 km SSW of Kokopo, Papua New Guinea, at a depth of 111.2 km and coordinates -5.0967°, 151.8667°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
