2021-11-26 23:04:31 UTC (2021-11-26) · approx. 4:04 PM UTC-7 local
On November 26, 2021 at 23:04 UTC, a magnitude 3.3 shallow crustal earthquake struck 54 km NW of Toyah, Texas, at a depth of 6.8 km and coordinates 31.6078°, -104.2571°.
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.
