On June 25, 2025 at 21:18 UTC, a magnitude 3.4 shallow crustal earthquake struck 10 km NW of Woodston, Kansas, at a depth of 12.9 km and coordinates 39.5084°, -99.1903°.

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
