M3.0 Earthquake near western Texas — October 21, 2023
2023-10-21 19:51:33 UTC (2023-10-21) · approx. 12:51 PM UTC-7 local
On October 21, 2023 at 19:51 UTC, a magnitude 3.0 shallow crustal earthquake struck near western Texas, at a depth of 6.7 km and coordinates 31.7210°, -103.9960°.
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.
