On June 15, 2026 at 22:18 UTC, a magnitude 4.2 intermediate depth earthquake struck 72 km WNW of Kandrian, Papua New Guinea, at a depth of 77.5 km and coordinates -6.0264°, 148.9130°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
