On February 24, 2022 at 06:28 UTC, a magnitude 5.3 shallow crustal earthquake struck 142 km SSW of Kokopo, Papua New Guinea, at a depth of 25.1 km and coordinates -5.5895°, 151.9257°.

Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Papua New Guinea, a region characterized by the collision and subduction of the Pacific, Australian, and Solomon Sea plates. View all earthquakes in Papua New Guinea.
