On December 11, 2023 at 17:36 UTC, a magnitude 5.0 shallow crustal earthquake struck 98 km SE of Kandrian, Papua New Guinea, at a depth of 10.0 km and coordinates -6.9241°, 150.0725°. This earthquake was detected by 60 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
