2026-02-19 19:57:24 UTC (2026-02-19) · approx. 12:57 PM UTC-7 local
On February 19, 2026 at 19:57 UTC, a magnitude 2.6 shallow crustal earthquake struck 8 km ENE of Calumet, Oklahoma, at a depth of 5.6 km and coordinates 35.6242°, -98.0310°.
Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 138 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 40 m — a useful intuition for the size of the slip patch on the fault.
