M4.7 Earthquake 10 km S of La Mesa, Panama — October 14, 2026
2026-10-14 05:09:35 UTC (6 hours ago) · approx. 12:09 AM UTC-5 local
Aftershock of the M5.0 mainshock.
On October 14, 2026 at 05:09 UTC, a magnitude 4.7 shallow crustal earthquake struck 10 km S of La Mesa, Panama, at a depth of 10.0 km and coordinates 7.5657°, -80.6021°. This earthquake was detected by 41 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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 5.0 mainshock that occurred 3 days ago 3 km NW of Flores, Panama. Since the mainshock, the USGS has recorded 19 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 4.7 earthquake near La Mesa, Panama?
The magnitude 4.7 earthquake that struck 10 km S of La Mesa, Panama on October 14, 2026 at 05:09 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 7.5657°, -80.6021°, which is 10 km S of La Mesa, Panama.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.7 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 4.7 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 3 km NW of Flores, Panama. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
