On April 8, 2021 at 19:41 UTC, a magnitude 4.4 intermediate depth earthquake struck 93 km SSE of Lakatoro, Vanuatu, at a depth of 218.3 km and coordinates -16.8553°, 167.8068°.
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.
