An earthquake of magnitude 6.8 struck off the coast of south-central Chile on Sunday, the European Mediterranean Seismological Centre (EMSC) said, but Chilean officials immediately discarded the risk of a tsunami.
There were no initial reports of damage immediately following the quake.
The strong tremor took place at a depth of 10 km (6.21 miles), EMSC said, and about 163 km (100 miles) west-northwest of Valdivia in the Pacific Ocean.
