Heads Up! A major earthquake has hit the southern coasts of Chile and Argentina!
The Big One: On Friday, May 2, 2025, an earthquake with a magnitude of 7.4 rocked the region. The epicenter was located approximately 219 kilometers south of Ushuaia, Argentina, in the ocean.
Rumble in the Deep: This powerful undersea shock occurred at a depth of 10 km[1][2].
Tsunami Alerts and Evacuations: As a precaution, Chile's National Service of Prevention and Response to Natural Disasters announced evacuations in coastal areas of Magallanes, due to the potential threat of a tsunami[1]. Residents in heavily populated cities like Punta Arenas, Chile, and Ushuaia, Argentina, were advised to move to safe zones[1].
Aftershocks: While there aren't specific reports on significant aftershocks, monitoring for potential aftershocks following such a significant event is essential[1].
Impact on Coastal Areas:
Magallanes Region, Chile:- Evacuations: The Chilean authorities issued evacuation alerts for the entire coastal section of the Strait of Magellan due to tsunami warnings[1].- Preparations: Residents were advised to move to safe zones, with many seeking shelters[1].
Punta Arenas, Chile:- Response: The streets quickly filled with residents moving to shelters. Many residents were seen carrying bags, indicating their readiness to relocate temporarily[1].- Location: Punta Arenas is a city in Chilean Patagonia and on the Strait of Magellan, which connects the Atlantic and Pacific Oceans.
Ushuaia, Argentina:- Distance and Impact: Although Ushuaia itself did not experience significant direct impacts, Argentina's Tierra del Fuego province suspended water activities and navigation as a precautionary measure[1][2].
Overall Response: Chilean President Gabriel Boric assured that all resources were available to respond to potential emergencies, emphasizing the importance of readiness and compliance with authority instructions[1].
