Magnitude 7.5 quake struck between South America and Antarctica on August 22, 2025.
A strong 7.5-magnitude earthquake shook the Drake Passage on Friday, August 22, 2025, according to seismic reports. The quake was recorded at a shallow depth of nearly 10 kilometers, making it strongly felt in the remote oceanic region located between Cape Horn at South America’s southern tip and the northern reaches of Antarctica.
Early assessments briefly triggered a tsunami alert for parts of Chile, but monitoring agencies later confirmed that the event does not pose a tsunami risk to coastal communities.
The affected zone lies far from major population centers, and as of now, no damage or casualties have been reported. Scientists note that the Drake Passage is seismically active due to the interaction of the South American and Antarctic tectonic plates.
Authorities are continuing to monitor the situation, but the current outlook suggests that the tremor’s impact is limited to the ocean region.
