On October 25, 2020 at 22:44 UTC, a magnitude 4.4 intermediate depth earthquake struck 19 km SE of Ishqoshim, Tajikistan, at a depth of 94.3 km and coordinates 36.6053°, 71.7720°.

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.
