On October 15, 2022 at 01:15 UTC, a magnitude 5.1 shallow crustal earthquake struck in the New Ireland region, Papua New Guinea, at a depth of 24.6 km and coordinates -5.3673°, 153.0291°. This earthquake was detected by 64 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
