On January 16, 2026 at 22:07 UTC, a magnitude 4.8 intermediate depth earthquake struck 44 km SSW of Angoram, Papua New Guinea, at a depth of 131.1 km and coordinates -4.4366°, 143.9305°. This earthquake was detected by 69 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
