Felt by 11 people across nearby locations.
On July 16, 2023 at 13:44 UTC, a magnitude 5.1 shallow crustal earthquake struck 3 km W of Paso de Arena, Mexico, at a depth of 62.7 km and coordinates 18.3051°, -100.8784°. This earthquake was detected by 104 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 404, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — 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.
