2025-09-14 13:34:05 UTC (2025-09-14) · approx. 11:34 PM UTC+10 local
On September 14, 2025 at 13:34 UTC, a magnitude 4.0 shallow crustal earthquake struck 200 km SW of Panguna, Papua New Guinea, at a depth of 10.0 km and coordinates -7.8188°, 154.4747°.
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.
