On November 2, 2021 at 23:25 UTC, a magnitude 3.9 shallow crustal earthquake struck 5 km SSW of Kragujevac, Serbia, at a depth of 10.0 km and coordinates 43.9764°, 20.8848°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
