ARGENTINA (CBS SF) — A preliminary magnitude 6.2 earthquake struck northern Argentina early Wednesday morning, according to the U.S. Geological Survey.

The quake was very deep, at over 100 miles below the surface and struck in a remote mountainous region near the borders with Chile and Bolivia.

Deeper quakes usually have less damage and shaking at the surface for their magnitude.

There are no reports of damage or injuries at this point. For commparison, the Napa quake from August registered a 6.0, significantly weaker than the quake this morning.
