On July 24, 2021 at 23:11 UTC, a magnitude 4.4 intermediate depth earthquake struck 21 km ESE of Khorugh, Tajikistan, at a depth of 110.5 km and coordinates 37.4372°, 71.7817°.
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.
