2021-11-03 16:22:06 UTC (2021-11-03) · approx. 3:22 AM UTC+11 local
On November 3, 2021 at 16:22 UTC, a magnitude 4.0 deep-focus earthquake struck 151 km NE of Sola, Vanuatu, at a depth of 542.8 km and coordinates -13.1086°, 168.7132°.
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.
