On February 3, 2025 at 21:11 UTC, a magnitude 4.4 shallow crustal earthquake struck 130 km WNW of Port-Olry, Vanuatu, at a depth of 10.0 km and coordinates -14.5452°, 165.9701°.
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.
