Mexico experienced two moderate earthquakes early Thursday, September 25, 2025, according to the U.S. Geological Survey (USGS). The first tremor measured magnitude 5.7 and struck at 10:16 a.m. UTC, followed just five minutes later by a magnitude 5.1 quake. Both events were centered south-southwest of Emiliano Zapata and occurred at shallow depths of 10 kilometers, a factor that can sometimes amplify ground shaking.
Where Did the Earthquakes Occur?
Interactive maps released by the USGS show the quakes’ epicenters offshore along Mexico’s Pacific coast.
- First quake: 17.964°N, 105.802°W, about 180 km from Emiliano Zapata.
- Second quake: 18.117°N, 105.759°W, about 163 km from the same area.
These coordinates place both tremors within a seismically active zone caused by the interaction between the Cocos Plate and the North American Plate, two of the most active tectonic plates in the world.
As of Thursday morning, no reports of damage or injuries have been confirmed. The USGS issued a green PAGER alert, indicating a low likelihood of casualties or economic disruption. Its accompanying ShakeMap showed light shaking (level IV) near the offshore epicenters.
So far, no confirmed “Did You Feel It?” reports have been submitted to the USGS. However, due to their offshore locations, the quakes may have been lightly felt in coastal communities of Jalisco and Colima, though this remains unverified. Citizen scientists are encouraged to contribute felt reports to help refine impact assessments.
Mexico sits atop a complex network of active fault lines and tectonic boundaries, making it one of the most seismically active countries on the planet. While Thursday’s quakes were moderate and offshore, they serve as a reminder of the region’s vulnerability to larger, more destructive seismic events.
