On June 12, 2020 at 17:15 UTC, a magnitude 4.3 shallow crustal earthquake struck north of Franz Josef Land, at a depth of 10.0 km and coordinates 87.0856°, 43.3199°.

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.
