2022-03-18 19:53:50 UTC (2022-03-18) · approx. 12:53 PM UTC-7 local
On March 18, 2022 at 19:53 UTC, a magnitude 4.4 shallow crustal earthquake struck 4 km SSE of El Conchero, Mexico, at a depth of 21.5 km and coordinates 16.9055°, -99.9498°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
