2022-09-21 22:36:37 UTC (2022-09-21) · approx. 9:36 AM UTC+11 local
On September 21, 2022 at 22:36 UTC, a magnitude 4.3 intermediate depth earthquake struck near Vanuatu, at a depth of 206.0 km and coordinates -13.2349°, 167.0860°.
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.
