On February 15, 2025 at 17:42 UTC, a magnitude 4.4 intermediate depth earthquake struck 157 km SSE of Isangel, Vanuatu, at a depth of 159.5 km and coordinates -20.9121°, 169.6822°.
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.
