A 6.4 magnitude earthquake has struck Argentina, according to the US Geological Survey.
It is the second quake to hit the region in eight days.
The centre of the quake hit 25 kilometers southwest of San Juan, the north western region of the country and close to Chile.
The quake was originally reported by the USGS as a magnitude 6.7 but was later downgraded.
The USGS said there was a low likelihood of damage or casualties.
It was measured as fairly deep below ground, striking more than 115 kilometers below the Earth's surface, which lessens the effects.
On 13 November a 6.2 magnitude quake hit northwestern Argentina around 8am local time, at a depth of about 99 kilometers, and no serious injuries were reported.
