On May 25, 2026 at 15:00 UTC, a magnitude 5.0 shallow crustal earthquake struck 104 km ESE of Kokopo, Papua New Guinea, at a depth of 66.8 km and coordinates -4.7343°, 153.1260°. This earthquake was detected by 68 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.
