On February 8, 2022 at 19:48 UTC, a magnitude 4.5 shallow crustal earthquake struck north of Severnaya Zemlya, at a depth of 10.0 km and coordinates 84.1825°, 108.0265°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
