On September 20, 2020 at 20:41 UTC, a magnitude 4.5 intermediate depth earthquake struck 52 km ENE of Murghob, Tajikistan, at a depth of 145.6 km and coordinates 38.3013°, 74.5420°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
