M5.0 Earthquake 95 km SW of Ocós, Guatemala — July 17, 2026
2026-07-17 14:56:38 UTC (2026-07-17) · approx. 8:56 AM UTC-6 local
Aftershock of the M5.5 mainshock.
On July 17, 2026 at 14:56 UTC, a magnitude 5.0 shallow crustal earthquake struck 95 km SW of Ocós, Guatemala, at a depth of 10.0 km and coordinates 13.8567°, -92.7648°. This earthquake was detected by 39 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — 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 5.5 mainshock that occurred 11 days ago 81 km SW of Puerto Madero, Mexico. Since the mainshock, the USGS has recorded 23 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 5.0 earthquake near Ocós, Guatemala?
The magnitude 5.0 earthquake that struck 95 km SW of Ocós, Guatemala on July 17, 2026 at 14:56 UTC had a depth of 10.0 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 13.8567°, -92.7648°, which is 95 km SW of Ocós, Guatemala.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.5 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier 81 km SW of Puerto Madero, Mexico. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
