M4.5 Earthquake 45 km SSE of Pedasí, Panama — October 9, 2026
2026-10-09 23:54:22 UTC (1 hour ago) · approx. 6:54 PM UTC-5 local
Felt by 1 person across nearby locations. Aftershock of the M5.4 mainshock.
On October 9, 2026 at 23:54 UTC, a magnitude 4.5 shallow crustal earthquake struck 45 km SSE of Pedasí, Panama, at a depth of 10.0 km and coordinates 7.1444°, -79.8903°. This earthquake was detected by 36 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 5.4 mainshock that occurred 2 hours ago 9 km SSE of Los Asientos, Panama. Since the mainshock, the USGS has recorded 3 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 Pedasí, Panama?
The magnitude 4.5 earthquake that struck 45 km SSE of Pedasí, Panama on October 9, 2026 at 23:54 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 7.1444°, -79.8903°, which is 45 km SSE of Pedasí, 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 M5.4 one earlier?
No. This magnitude 4.5 earthquake is an aftershock of the larger magnitude 5.4 mainshock that occurred earlier 9 km SSE of Los Asientos, Panama. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
