On February 21, 2024 at 18:20 UTC, a magnitude 4.1 intermediate depth earthquake struck 33 km E of Farkhār, Afghanistan, at a depth of 229.9 km and coordinates 36.5331°, 70.2323°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
