On August 8, 2021 at 21:10 UTC, a magnitude 4.0 shallow crustal earthquake struck 8 km SSE of Laktaši, Bosnia and Herzegovina, at a depth of 9.1 km and coordinates 44.8351°, 17.3491°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
