On April 14, 2023 at 18:09 UTC, a magnitude 5.1 intermediate depth earthquake struck near New Guinea, Papua New Guinea, at a depth of 85.8 km and coordinates -4.4712°, 143.2100°. This earthquake was detected by 182 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 401, 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.
