M4.6 Earthquake 57 km SSW of Champerico, Guatemala — January 22, 2024
2024-01-22 21:52:54 UTC (2024-01-22) · approx. 3:52 PM UTC-6 local
0Aftershock of the M5.0 mainshock.
On January 22, 2024 at 21:52 UTC, a magnitude 4.6 shallow crustal earthquake struck 57 km SSW of Champerico, Guatemala, at a depth of 35.3 km and coordinates 13.8003°, -92.0793°.0 This earthquake was detected by 107 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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 26 days ago 60 km SW of Champerico, Guatemala. Since the mainshock, the USGS has recorded 1 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 4.6 earthquake near Champerico, Guatemala?
The magnitude 4.6 earthquake that struck 57 km SSW of Champerico, Guatemala on January 22, 2024 at 21:52 UTC had a depth of 35.3 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 13.8003°, -92.0793°, which is 57 km SSW of Champerico, Guatemala.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 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 4.6 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 60 km SW of Champerico, Guatemala. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
