On March 15, 2023 at 20:43 UTC, a magnitude 2.8 shallow crustal earthquake struck 13 km NW of Pawnee, Oklahoma, at a depth of 6.4 km and coordinates 36.4228°, -96.9118°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 256 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 53 m — a useful intuition for the size of the slip patch on the fault.
