A powerful earthquake with a preliminary magnitude of 7.5 struck in the early morning hours of May 2, 2025, approximately 219 kilometers south of Ushuaia, Argentina, near the remote region of Cape Horn. The United States Geological Survey (USGS) recorded the quake at a shallow depth of 10 kilometers, which increases the likelihood of strong ground shaking near the epicenter.
The tremor occurred at the convergence of major tectonic boundaries where the South American, Scotia, and Antarctic plates interact, a seismically active zone known for generating significant geological activity. Early indicators from the map place the epicenter offshore in the Drake Passage, not far from the southern tip of South America.
As of now, there are no immediate reports of damage or casualties from populated areas like Ushuaia or Punta Arenas. However, given the magnitude and shallow depth, authorities are monitoring for possible aftershocks or tsunami threats, though no official tsunami alert has been issued at the time of reporting.
Emergency teams and geological experts are closely tracking the situation.
Update
Tsunami warning and evacuation orders have been issued for coastal areas of Magallanes, Chile, following a 7.5-magnitude earthquake near Ushuaia, Argentina.
