On February 4, 2023 at 21:24 UTC, a magnitude 4.2 intermediate depth earthquake struck 27 km SSW of Khorugh, Tajikistan, at a depth of 113.7 km and coordinates 37.2483°, 71.4678°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
