On October 10, 2023 at 17:17 UTC, a magnitude 3.0 shallow crustal earthquake struck 8 km SSW of Falls City, Texas, at a depth of 7.6 km and coordinates 28.9170°, -98.0650°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
