On December 10, 2022 at 21:46 UTC, a magnitude 4.4 intermediate depth earthquake struck 53 km WSW of Panguna, Papua New Guinea, at a depth of 71.9 km and coordinates -6.4494°, 155.0210°.

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.
