M4.0 Earthquake 17 km S of Puerto Madero, Mexico — June 22, 2024
2024-06-22 22:29:05 UTC (2024-06-22) · approx. 4:29 PM UTC-6 local
On June 22, 2024 at 22:29 UTC, a magnitude 4.0 shallow crustal earthquake struck 17 km S of Puerto Madero, Mexico, at a depth of 48.8 km and coordinates 14.5645°, -92.4399°.
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 5.9 mainshock that occurred 15 days ago 50 km WSW of Brisas Barra de Suchiate, Mexico. Since the mainshock, the USGS has recorded 11 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 17 km S of Puerto Madero, Mexico on June 22, 2024 at 22:29 UTC had a depth of 48.8 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 M5.9 one earlier?
No. This magnitude 4.0 earthquake is an aftershock of the larger magnitude 5.9 mainshock that occurred earlier 50 km WSW of Brisas Barra de Suchiate, Mexico. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
