On July 19, 2020 at 22:21 UTC, a magnitude 4.1 intermediate depth earthquake struck 34 km SSW of Jurm, Afghanistan, at a depth of 235.1 km and coordinates 36.5686°, 70.7276°.

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.
