On May 15, 2023 at 21:28 UTC, a magnitude 4.1 intermediate depth earthquake struck in the eastern New Guinea region, Papua New Guinea, at a depth of 110.6 km and coordinates -5.9858°, 147.1134°.
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.
