2023-05-13 22:36:34 UTC (2023-05-13) · approx. 9:36 AM UTC+11 local
On May 13, 2023 at 22:36 UTC, a magnitude 4.0 intermediate depth earthquake struck 106 km ESE of Lakatoro, Vanuatu, at a depth of 212.4 km and coordinates -16.6320°, 168.2509°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
