BREAKING: Magnitude-6.8 Earthquake Rocks Chile

Two major earthquakes rocked Chile on Saturday.

The magnitude-6.8 temblor occurred at 4:31 a.m. local time Saturday and was centered 47 kilometers (29 miles) southwest of Ovalle, Chile, the United States Geological Survey reported.

The Chilean government initially issued a tsunami warning in the area of the earthquake but later canceled the warning. The quake was the strongest felt in the regions from Atacama to Maule, the government reported on its Twitter feed; it was also felt in parts of neighboring Argentina.

Electrical and telephone service was not affected in the Canela area, according to the municipality's Twitter feed.

A 5.8-magnitude earthquake about 30 minutes before the larger temblor, the USGS said. Chile's National Seismological Center recorded that quake as a 6.0 magnitude.

The region was struck by a magnitude-8.3 earthquake on Sept. 16, 2015. At least 13 people were killed as a result of that earthquake.
