On November 12, 2023 at 09:48 UTC, a magnitude 5.2 shallow crustal earthquake struck 129 km WNW of Rabaul, Papua New Guinea, at a depth of 10.0 km and coordinates -3.7633°, 151.0852°. This earthquake was detected by 76 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
