On April 25, 2022 at 16:31 UTC, a magnitude 4.0 shallow crustal earthquake struck 10 km SW of Blagoevgrad, Bulgaria, at a depth of 8.2 km and coordinates 41.9478°, 23.0187°.
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.
