M4.3 Earthquake 53 km SW of Champerico, Guatemala — March 15, 2025
2025-03-15 21:00:24 UTC (2025-03-15) · approx. 3:00 PM UTC-6 local
On March 15, 2025 at 21:00 UTC, a magnitude 4.3 shallow crustal earthquake struck 53 km SW of Champerico, Guatemala, at a depth of 30.2 km and coordinates 13.9004°, -92.1936°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 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 5.0 mainshock that occurred 12 days ago 87 km SSW of Ocós, Guatemala. Since the mainshock, the USGS has recorded 2 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 4.3 earthquake near Champerico, Guatemala?
The magnitude 4.3 earthquake that struck 53 km SW of Champerico, Guatemala on March 15, 2025 at 21:00 UTC had a depth of 30.2 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 4.3 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.0 one earlier?
No. This magnitude 4.3 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 87 km SSW of Ocós, Guatemala. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
