On October 12, 2024 at 18:43 UTC, a magnitude 4.1 shallow crustal earthquake struck 40 km S of Kandrian, Papua New Guinea, at a depth of 51.6 km and coordinates -6.5717°, 149.5329°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
