On January 3, 2026 at 07:06 UTC, a magnitude 4.7 deep-focus earthquake struck 203 km E of Kokopo, Papua New Guinea, at a depth of 371.8 km and coordinates -4.4907°, 154.0955°. This earthquake was detected by 81 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
