2023-01-12 16:01:25 UTC (2023-01-12) · approx. 10:01 AM UTC-6 local
On January 12, 2023 at 16:01 UTC, a magnitude 4.2 shallow crustal earthquake struck near Bay of Campeche, at a depth of 9.8 km and coordinates 19.6248°, -92.4468°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
