On November 21, 2024 at 15:38 UTC, a magnitude 2.9 shallow crustal earthquake struck 10 km E of Dilley, Texas, at a depth of 4.8 km and coordinates 28.6840°, -99.0700°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
