2021-05-23 22:14:55 UTC (2021-05-23) · approx. 10:14 PM UTC+0 local
On May 23, 2021 at 22:14 UTC, a magnitude 4.6 shallow crustal earthquake struck near Norwegian Sea, at a depth of 10.0 km and coordinates 72.5824°, 3.5650°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
