2021-05-11 20:06:31 UTC (2021-05-11) · approx. 4:06 AM UTC+8 local
On May 11, 2021 at 20:06 UTC, a magnitude 4.7 shallow crustal earthquake struck east of Severnaya Zemlya, at a depth of 10.0 km and coordinates 78.9681°, 124.5785°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
