# Thousands of people were moved to higher ground in the coastal areas of Chile and Argentina after Chilean authorities issued a tsunami warning following a 7.4 magnitude earthquake off the country’s southern coast. The US Geological Survey said its epicentre was 219 kilometres from Ushuaia in Argentina, the world’s most southerly city. The earthquake struck at a shallow depth of 10 kilometres. Some 32 people also followed evacuation procedures in Chile’s Antarctic research bases. Chile is often affected by earthquakes, with three tectonic plates converging within its territory.
