Shallow magnitude 7.4 and 6.4 earthquakes south of Chile and Argentina, tsunami warning issued

mmmmmmmm
A 7.4 earthquake struck the Drake Passage, located between Cape Horn and Antarctica, at a depth of just 10 km (6 miles) on Friday, according to the United States Geological Survey. The quake triggered a tsunami warning, prompting Chile's National Disaster Prevention and Response Service to issue evacuation orders for coastal areas in the Magallanes region, located at the southern tip of the country.

Chile's President Gabriel Boric took to social media to urge evacuations, stating that all state resources would be mobilised to respond to the situation. Videos shared on social media showed residents calmly evacuating as sirens sounded in the background.

A magnitude 6.3 earthquake has struck near the coast of Ecuador, according to the European-Mediterranean Seismological Centre (EMSC).

The epicentre of the quake - which took place at about 6:45am local time (11:45 GMT) - was near the Pacific coast of the northwestern city of Esmeraldas, at a depth of 30km (18.6 miles), said the EMSC. Tremors were reported in 10 provinces of the country, even as far as the capital, Quito.

Images shared online show buildings visibly damaged in the earthquake. Damaged structures included 30 homes, a health centre and a military building, the facade of which partially collapsed, according to authorities.
