A 6.8-magnitude earthquake rocked Chile on Sunday, striking at a depth of 9.8 kilometres, according to the Chile's national emergency agency. The tremor struck at 15:57 (UTC), 67 kilometres west of the city of Constitucion.
The USGS initially reported a 7.2-magnitude earthquake.
There are no immediate reports of damage or casualties.
"There is a low likelihood of casualties and damage," the USGS said. "Overall, the population in this region resides in structures that are resistant to earthquake shaking, though vulnerable structures exist."

Several users of the web from Chile have shared videos in which chandeliers in their flats are shaking due to the earthquake.
The footage also shows shaking at what appears to be a transport hub.
Chile is located on the so-called Pacific "Ring of Fire" notorious for deadly quakes.
In February 2010, Chile was hit by a devastating 8.8-magnitude earthquake, triggering a tsunami that led to the deaths of more than 500 people.
