A 7.1-magnitude earthquake has struck off the coast of Chile, near the capital Santiago, the US Geological Survey said.
Monday’s quake was centred 38km west of the coastal city of Valparaiso at a depth of 10km below the seabed, the USGS said.
Buildings shook in Santiago, 115km away.
Chile’s emergency services office said no damage to infrastructure was immediately reported and authorities were discounting the possibility of a tsunami.
Chile lies on what is known as the “Ring of Fire” – an arc of fault lines that circles the Pacific Basin and is prone to frequent earthquakes and volcanic eruptions.
The north of the country was struck by an 8.3 temblor followed by a tsunami in September 2015, killing 15 people.
In 2010 another quake measuring 8.8, also followed by a tsunami, struck the centre and south of the country, killing more than 500 people.
