Felt by 4 people across nearby locations.
On July 23, 2023 at 18:23 UTC, a magnitude 4.7 shallow crustal earthquake struck 13 km SSE of Maravilla Tenejapa, Mexico, at a depth of 10.0 km and coordinates 16.0371°, -91.2293°. This earthquake was detected by 226 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 341, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
