On July 26, 2026 at 08:41 UTC, a magnitude 4.2 intermediate depth earthquake struck 35 km SW of Ashkāsham, Afghanistan, at a depth of 121.6 km and coordinates 36.4279°, 71.3005°.

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.
