On October 13, 2023 at 23:50 UTC, a magnitude 4.4 intermediate depth earthquake struck 60 km SE of Madang, Papua New Guinea, at a depth of 73.9 km and coordinates -5.6065°, 146.1747°.

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.
