M3.3 Earthquake 55 km NW of Toyah, Texas — January 5, 2024
2024-01-05 21:24:09 UTC (2024-01-05) · approx. 2:24 PM UTC-7 local
On January 5, 2024 at 21:24 UTC, a magnitude 3.3 shallow crustal earthquake struck 55 km NW of Toyah, Texas, at a depth of 6.8 km and coordinates 31.6770°, -104.1890°.
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.
