Executive Summary
- A 7.4 magnitude earthquake struck off the southern coasts of Chile and Argentina, triggering tsunami warnings and evacuations.
- The tsunami warning was later canceled after authorities determined that no tsunami was occurring, and people were allowed to return to their homes.
- No damage or casualties were reported, but the event highlighted Chile's earthquake preparedness and emergency response capabilities.
Event Overview
On Friday, a 7.4 magnitude earthquake struck off the southern coasts of Chile and Argentina, with its epicenter located in the Drake Passage. The earthquake triggered a tsunami warning, prompting evacuations along the Chilean coastline, including the Strait of Magellan and Antarctic areas, and the suspension of water activities in Ushuaia, Argentina. Although a tsunami warning was initially issued for coastal areas within 185-200 miles of the epicenter, it was later canceled after authorities determined that no tsunami was occurring. While the earthquake caused concern and disruption, no damage or casualties were reported.
