Felt by 1 person across nearby locations.
On September 15, 2025 at 12:36 UTC, a magnitude 4.5 shallow crustal earthquake struck 6 km NW of Santa Rosa, Mexico, at a depth of 53.5 km and coordinates 16.3620°, -95.1391°. This earthquake was detected by 91 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
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.
