On July 8, 2022 at 03:37 UTC, a magnitude 5.3 shallow crustal earthquake struck 105 km SSW of Kokopo, Papua New Guinea, at a depth of 58.9 km and coordinates -5.2022°, 151.8614°. This earthquake was detected by 92 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 434, placing it among routine seismic activity.

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.
