M4.0 Earthquake 6 km SW of Puerto Madero, Mexico — May 30, 2025
2025-05-30 23:31:39 UTC (2025-05-30) · approx. 5:31 PM UTC-6 local
On May 30, 2025 at 23:31 UTC, a magnitude 4.0 shallow crustal earthquake struck 6 km SW of Puerto Madero, Mexico, at a depth of 66.1 km and coordinates 14.6797°, -92.4688°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — 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 5.1 mainshock that occurred 1 day ago 43 km SW of Puerto Madero, Mexico. Since the mainshock, the USGS has recorded 10 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 4.0 earthquake near Puerto Madero, Mexico?
The magnitude 4.0 earthquake that struck 6 km SW of Puerto Madero, Mexico on May 30, 2025 at 23:31 UTC had a depth of 66.1 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.0 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 4.0 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 43 km SW of Puerto Madero, Mexico. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
