M4.5 Earthquake 9 km WNW of Flores, Panama — October 10, 2026
2026-10-10 04:33:03 UTC (1 hour ago) · approx. 11:33 PM UTC-5 local
Aftershock of the M6.0 mainshock.
On October 10, 2026 at 04:33 UTC, a magnitude 4.5 shallow crustal earthquake struck 9 km WNW of Flores, Panama, at a depth of 10.0 km and coordinates 7.5239°, -80.4791°. This earthquake was detected by 24 seismic stations with good 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 6.0 mainshock that occurred 1 hour ago 7 km N of La Tronosa, Panama. Since the mainshock, the USGS has recorded 7 aftershocks in this area. Aftershock activity is expected to continue for weeks to months as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 4.5 earthquake near Flores, Panama?
The magnitude 4.5 earthquake that struck 9 km WNW of Flores, Panama on October 10, 2026 at 04:33 UTC had a depth of 10.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 7.5239°, -80.4791°, which is 9 km WNW of Flores, Panama.
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 M6.0 one earlier?
No. This magnitude 4.5 earthquake is an aftershock of the larger magnitude 6.0 mainshock that occurred earlier 7 km N of La Tronosa, Panama. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
