The earthquake took place in Argentina's San Juan province.
An earthquake of magnitude 6.8 has struck Argentina's San Juan province, the GFZ German Research Center for Geosciences said.

The quake hit the west-central province late on Monday at a depth of 10 km, GFZ said.

The US Tsunami Warning System said no tsunami warning has been issued for the earthquake.

There were no immediate reports of serious damages or victims.

The US Geological Survey said the quake had a preliminary magnitude of 6.4 and its epicentre was 27.6 km southwest of the town of Porcito.

The quake was followed by a magnitude 5.0 aftershock about a quarter hour later, the USGS said.

"Many neighbours came down from the buildings and houses, went out into the street. The water in the pool moved like the sea," Ricardo, a resident of Mendoza city, told local newspaper Clarin.

Quake shakes Chile

Strong movement was felt in Chile's capital, Santiago, which is about 300 kilometres from the area hit by the quake.

Chilean officials said there was no damage reported in that nation.

Media in Argentina said electricity failed in the region around Porcito and some goods were shaken from supermarket shelves.
