M3.5 Earthquake 192km S of Estacion Coahuila, B.C., MX — December 17, 2021
2021-12-17 21:29:29 UTC (2021-12-17) · approx. 1:29 PM UTC-8 local
On December 17, 2021 at 21:29 UTC, a magnitude 3.5 shallow crustal earthquake struck 192km S of Estacion Coahuila, B.C., MX, at a depth of 6.0 km and coordinates 30.4775°, -114.7370°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 145 m — a useful intuition for the size of the slip patch on the fault.
