On November 22, 2025 at 16:51 UTC, a magnitude 4.4 shallow crustal earthquake struck 179 km NNE of Madang, Papua New Guinea, at a depth of 10.0 km and coordinates -3.7521°, 146.4766°.
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.
