M4.7 Earthquake 60 km WSW of Aquiles Serdán, Mexico — July 17, 2026
2026-07-17 13:20:34 UTC (2 hours ago) · approx. 7:20 AM UTC-6 local
Felt by 5 people across nearby locations. Aftershock of the M7.3 mainshock.
On July 17, 2026 at 13:20 UTC, a magnitude 4.7 shallow crustal earthquake struck 60 km WSW of Aquiles Serdán, Mexico, at a depth of 35.0 km and coordinates 14.6493°, -92.9865°. This earthquake was detected by 50 seismic stations with moderate 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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 7.3 mainshock that occurred 58 minutes ago 48 km SW of Aquiles Serdán, Mexico. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for months to years as stresses on surrounding faults redistribute.
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.

Common Questions
How strong was the magnitude 4.7 earthquake near Aquiles Serdán, Mexico?
The magnitude 4.7 earthquake that struck 60 km WSW of Aquiles Serdán, Mexico on July 17, 2026 at 13:20 UTC had a depth of 35.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 14.6493°, -92.9865°, which is 60 km WSW of Aquiles Serdán, Mexico. View all earthquakes in Mexico.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.7 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M7.3 one earlier?
No. This magnitude 4.7 earthquake is an aftershock of the larger magnitude 7.3 mainshock that occurred earlier 48 km SW of Aquiles Serdán, Mexico. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 4.7 event is significantly smaller than that historical record.
