On December 24, 2021 at 21:39 UTC, a magnitude 4.1 shallow crustal earthquake struck 53 km WNW of K?zer?n, Iran, at a depth of 10.0 km and coordinates 29.7481°, 51.1246°.
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.
