2022-10-22 23:15:38 UTC (2022-10-22) · approx. 10:15 AM UTC+11 local
On October 22, 2022 at 23:15 UTC, a magnitude 4.4 shallow crustal earthquake struck 79 km WNW of Sola, Vanuatu, at a depth of 10.3 km and coordinates -13.6613°, 166.8537°.
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.
