Felt by 1 person across nearby locations.
On May 23, 2021 at 21:11 UTC, a magnitude 4.6 shallow crustal earthquake struck 84 km W of Campo Pesquero el Colorado, Mexico, at a depth of 10.0 km and coordinates 25.6855°, -110.1543°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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 Colorado.
