M4.3 Earthquake north of Severnaya Zemlya — February 2, 2022
2022-02-02 22:14:54 UTC (2022-02-02) · approx. 6:14 AM UTC+8 local
On February 2, 2022 at 22:14 UTC, a magnitude 4.3 shallow crustal earthquake struck north of Severnaya Zemlya, at a depth of 10.0 km and coordinates 83.3480°, 115.8766°.
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.
