The U.S. Geological Survey says a 5.7 magnitude earthquake has shaken northern Chile. 

Authorities say the quake struck late Wednesday and was centered 65 kilometers east-northeast of the Calama area.  A spokesman for a copper mine in the area said the quake had no impact.

Last month, a 7.7 magnitude earthquake damaged homes and buildings in northern Chile, leaving two people dead, dozens injured and 15,000 people displaced.  The tremor was felt as far away as the capital, Santiago, as well as neighboring Peru and Bolivia.
