On October 9, 2023 at 18:23 UTC, a magnitude 5.0 shallow crustal earthquake struck 15 km SE of Stropkov, Slovakia, at a depth of 6.5 km and coordinates 49.0950°, 21.7882°. This earthquake was detected by 173 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 661, making it a moderate-impact event.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
