2022-08-17 20:08:00 UTC (2022-08-17) · approx. 1:08 PM UTC-7 local
On August 17, 2022 at 20:08 UTC, a magnitude 2.8 shallow crustal earthquake struck 17 km NNE of Hermleigh, Texas, at a depth of 7.8 km and coordinates 32.7676°, -100.6551°.
Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 203 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 48 m — a useful intuition for the size of the slip patch on the fault.
