On July 11, 2026 at 06:11 UTC, a magnitude 4.9 shallow crustal earthquake struck 2 km W of Polkowice, Poland, at a depth of 5.0 km and coordinates 51.5038°, 16.0437°. This earthquake was detected by 92 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 375, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
