On April 29, 2025 at 18:33 UTC, a magnitude 2.9 shallow crustal earthquake struck 4 km WSW of Bytom, Poland, at a depth of 5.0 km and coordinates 50.3327°, 18.8706°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
