On October 8, 2023 at 22:42 UTC, a magnitude 4.4 shallow crustal earthquake struck 15 km WNW of Tashanta, Russia, at a depth of 10.0 km and coordinates 49.7473°, 88.9856°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
