On August 23, 2023 at 22:03 UTC, a magnitude 4.3 intermediate depth earthquake struck 66 km NW of Sola, Vanuatu, at a depth of 165.2 km and coordinates -13.4611°, 167.1107°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
