On September 23, 2024 at 22:13 UTC, a magnitude 3.3 shallow crustal earthquake struck 16 km SW of Falls City, Texas, at a depth of 5.1 km and coordinates 28.8610°, -98.1230°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
