M4.7 Earthquake near Drake Passage — December 5, 2025
2025-12-05 19:24:33 UTC (2025-12-05) · approx. 3:24 PM UTC-4 local
Aftershock of the M5.0 mainshock.
On December 5, 2025 at 19:24 UTC, a magnitude 4.7 shallow crustal earthquake struck near Drake Passage, at a depth of 10.0 km and coordinates -60.1610°, -62.1152°. This earthquake was detected by 72 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 21 days ago near Drake Passage. 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 4.7 earthquake near Drake Passage?
The magnitude 4.7 earthquake that struck near Drake Passage on December 5, 2025 at 19:24 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 -60.1610°, -62.1152°, which is near Drake Passage.
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 near Drake Passage. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks.
