M4.8 Earthquake 231 km S of Burica, Panama — June 28, 2024
2024-06-28 22:01:56 UTC (2024-06-28) · approx. 4:01 PM UTC-6 local
Aftershock of the M5.1 mainshock.
On June 28, 2024 at 22:01 UTC, a magnitude 4.8 shallow crustal earthquake struck 231 km S of Burica, Panama, at a depth of 10.0 km and coordinates 5.9482°, -82.6481°. This earthquake was detected by 124 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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 5.1 mainshock that occurred 7 days ago 238 km SSW of Río Grande, Panama. Since the mainshock, the USGS has recorded 0 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 4.8 earthquake near Burica, Panama?
The magnitude 4.8 earthquake that struck 231 km S of Burica, Panama on June 28, 2024 at 22:01 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 5.9482°, -82.6481°, which is 231 km S of Burica, Panama.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.8 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 238 km SSW of Río Grande, Panama. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
