On October 18, 2024 at 18:34 UTC, a magnitude 3.1 shallow crustal earthquake struck 34 km WSW of Ackerly, Texas, at a depth of 6.4 km and coordinates 32.4120°, -102.0590°.

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.
