On August 14, 2025 at 23:35 UTC, a magnitude 4.4 shallow crustal earthquake struck 45 km S of Port-Vila, Vanuatu, at a depth of 56.7 km and coordinates -18.1429°, 168.3484°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
