On September 12, 2026 at 14:32 UTC, a magnitude 4.4 deep-focus earthquake struck 116 km NW of Arawa, Papua New Guinea, at a depth of 313.4 km and coordinates -5.4603°, 154.8476°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
