On August 7, 2021 at 20:03 UTC, a magnitude 4.5 shallow crustal earthquake struck 22 km ENE of Rasht, Tajikistan, at a depth of 10.0 km and coordinates 39.1061°, 70.6156°.
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.
