2021-05-15 18:21:26 UTC (2021-05-15) · approx. 12:21 PM UTC-6 local
On May 15, 2021 at 18:21 UTC, a magnitude 4.2 intermediate depth earthquake struck 12 km E of El Bajío, Mexico, at a depth of 106.1 km and coordinates 16.8744°, -94.9208°.
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.
