2022-04-18 21:20:53 UTC (2022-04-18) · approx. 10:20 PM UTC+1 local
On April 18, 2022 at 21:20 UTC, a magnitude 4.3 shallow crustal earthquake struck near Norwegian Sea, at a depth of 10.0 km and coordinates 73.4645°, 10.4328°.
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.
