2020-11-22 21:46:20 UTC (2020-11-22) · approx. 8:46 AM UTC+11 local
On November 22, 2020 at 21:46 UTC, a magnitude 4.4 shallow crustal earthquake struck southeast of the Loyalty Islands, at a depth of 10.0 km and coordinates -22.4173°, 172.0038°.
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.
