On April 27, 2022 at 18:53 UTC, a magnitude 4.4 shallow crustal earthquake struck 6 km WSW of Rudna, Poland, at a depth of 5.0 km and coordinates 51.4957°, 16.1715°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
