M4.6 Earthquake 5 km SE of Argelia, Colombia — March 9, 2026
2026-03-09 22:11:22 UTC (2026-03-09) · approx. 5:11 PM UTC-5 local
Felt by 2 people across nearby locations. Aftershock of the M5.0 mainshock.
On March 9, 2026 at 22:11 UTC, a magnitude 4.6 intermediate depth earthquake struck 5 km SE of Argelia, Colombia, at a depth of 114.5 km and coordinates 4.6844°, -76.0839°. This earthquake was detected by 43 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 13 days ago 16 km W of San José del Palmar, Colombia. Since the mainshock, the USGS has recorded 4 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 Argelia, Colombia?
The magnitude 4.6 earthquake that struck 5 km SE of Argelia, Colombia on March 9, 2026 at 22:11 UTC had a depth of 114.5 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 4.6844°, -76.0839°, which is 5 km SE of Argelia, Colombia.
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 16 km W of San José del Palmar, Colombia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
