On August 2, 2021 at 21:39 UTC, a magnitude 4.5 shallow crustal earthquake struck 115 km SW of An?r Darah, Afghanistan, at a depth of 10.0 km and coordinates 32.1646°, 60.6425°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Afghanistan, a region characterized by the Hindu Kush deep seismic zone, where remnant subducted lithosphere produces intermediate-depth earthquakes at 150-300 km. View all earthquakes in Afghanistan.
