San Antonio de los Cobres, Argentina — A magnitude 4.6 earthquake struck deep beneath the high desert of northwestern Argentina late Saturday morning, shaking ground near the town of San Antonio de los Cobres in Salta Province.

What happened:

A magnitude 4.6 earthquake struck about 62 kilometers, or roughly 39 miles, west-northwest of San Antonio de los Cobres at 10:36 AM Central Time on Saturday, November 14. The U.S. Geological Survey placed the quake at a depth of about 198 kilometers, or roughly 123 miles, beneath the Earth's surface. The epicenter sits in the rugged Andean highlands of Salta Province, near the border with Chile.

Impacts:

Because the quake struck so deep underground, shaking at the surface was likely light. The Geological Survey has not listed any damage reports with this quake, and no tsunami threat was issued.

What to do:

Drop, cover, and hold on during shaking, and stay clear of windows and heavy objects that could fall.

After the shaking stops, check for hazards such as gas leaks, damaged wiring, and cracked walls before going back inside a building.

Stay alert for aftershocks, which can follow a quake like this one and catch people off guard.
