M3.7 Earthquake near western Texas — October 21, 2022
2022-10-21 19:57:58 UTC (2022-10-21) · approx. 12:57 PM UTC-7 local
On October 21, 2022 at 19:57 UTC, a magnitude 3.7 shallow crustal earthquake struck near western Texas, at a depth of 6.7 km and coordinates 31.6724°, -104.4016°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
