On April 13, 2024 at 18:25 UTC, a magnitude 4.0 shallow crustal earthquake struck 73 km WSW of Kandrian, Papua New Guinea, at a depth of 37.9 km and coordinates -6.5238°, 148.9673°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
