On February 16, 2026 at 22:34 UTC, a magnitude 3.1 shallow crustal earthquake struck 5 km E of Calumet, Oklahoma, at a depth of 10.3 km and coordinates 35.5951°, -98.0584°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
