On August 2, 2025 at 22:33 UTC, a magnitude 2.7 shallow crustal earthquake struck 3 km E of Assaria, Kansas, at a depth of 5.0 km and coordinates 38.6855°, -97.5596°.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 m — a useful intuition for the size of the slip patch on the fault.
