SANTIAGO, Chile - A moderate earthquake registering a 6.3 magnitude rattled Chile Monday, though there were no reported injuries.

Officials at the U.S. Geological Survey initially reported the quake near the northern city of Iquique registered 6.6.

There were, however some landslides blocking roads in the area, La Nacion reported online.

Quakes of varying degrees often hit the mountainous South American country.

The nation's and possibly the world's strongest earthquake of the 20th century hit Valdivia, Chile, in May 1960, registering 9.5. An increase of 1 magnitude means an earthquake is 10 times stronger.

An estimated 2,000 were killed and 2 million lost their homes in that quake.
