On September 6, 2023 at 21:57 UTC, a magnitude 4.1 intermediate depth earthquake struck 88 km WNW of Sola, Vanuatu, at a depth of 105.2 km and coordinates -13.5169°, 166.8218°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
