2022-01-06 21:44:49 UTC (2022-01-06) · approx. 3:44 PM UTC-6 local
On January 6, 2022 at 21:44 UTC, a magnitude 4.5 intermediate depth earthquake struck 7 km SSW of San Isidro, Mexico, at a depth of 97.3 km and coordinates 15.6782°, -93.3823°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Mexico, a region characterized by the Middle America Trench, where the Cocos Plate subducts beneath the North American Plate. The nearest mapped fault system is the Middle America Trench. View all earthquakes in Mexico.
