On October 18, 2022 at 13:43 UTC, a magnitude 4.1 intermediate depth earthquake struck 55 km NW of Murghob, Tajikistan, at a depth of 124.3 km and coordinates 38.4568°, 73.4456°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
