M3.4 Earthquake 47 km W of Mentone, Texas — August 30, 2022
2022-08-30 20:49:52 UTC (2022-08-30) · approx. 1:49 PM UTC-7 local
On August 30, 2022 at 20:49 UTC, a magnitude 3.4 shallow crustal earthquake struck 47 km W of Mentone, Texas, at a depth of 6.2 km and coordinates 31.7062°, -104.0977°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
