2025-09-25 10:21:20 UTC (2025-09-25) · approx. 3:21 AM UTC-7 local
On September 25, 2025 at 10:21 UTC, a magnitude 5.3 shallow crustal earthquake struck 175 km SW of Emiliano Zapata, Mexico, at a depth of 10.0 km and coordinates 18.0806°, -105.9027°. This earthquake was detected by 60 seismic stations with good location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.

Has Mexico had earthquakes this big before?
The largest recorded earthquake in Mexico was the M8.1 Chiapas earthquake of September 8, 2017. Today's magnitude 5.3 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
