2022-10-02 22:19:14 UTC (2022-10-02) · approx. 4:19 PM UTC-6 local
On October 2, 2022 at 22:19 UTC, a magnitude 4.0 shallow crustal earthquake struck 164 km WSW of Puerto Madero, Mexico, at a depth of 10.0 km and coordinates 13.9926°, -93.7508°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
