On August 5, 2026 at 06:13 UTC, a magnitude 4.5 shallow crustal earthquake struck 84 km SW of Champerico, Guatemala, at a depth of 12.0 km and coordinates 13.7508°, -92.4623°. This earthquake was detected by 71 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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 4.5 earthquake near Champerico, Guatemala?

The magnitude 4.5 earthquake that struck 84 km SW of Champerico, Guatemala on August 5, 2026 at 06:13 UTC had a depth of 12.0 km. For context, this was a light earthquake commonly felt near the epicenter.

Where did the earthquake occur?

The earthquake epicenter was located at 13.7508°, -92.4623°, which is 84 km SW of Champerico, Guatemala.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.5 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 4.5 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.
