7.4 magnitude earthquake hits Argentina, Chile 

Chilean authorities have issued a tsunami warning and ordered evacuations after a magnitude 7.4 earthquake struck off the southern coasts of Chile and Argentina.

The Chilean National Service for Disaster Prevention and Response issued a “red alert” on Friday for coastal areas in its southernmost Magallanes region and the country’s Antarctic territory due to the tsunami risk.

In a post on its website, the agency said hundreds of people had been evacuated from a handful of communities, including the town of Puerto Williams.

“The National Disaster Prevention and Response System continues to assess the impact on people and damage to infrastructure and basic services,” it added.

No damage or casualties have been initially reported.

The earthquake struck Drake Passage between Cape Horn and Antarctica at a depth of just 10km (six miles), the United States Geological Survey said.
