According to the National Seismological Center of the University of Chile, the quake occurred at 1:15 p.m. local time (1715 GMT), 54 kilometers south of Diego de Almagro in the northern region of Atacama, about 950 kilometers north of Santiago.

The earthquake struck at a depth of 65 kilometers and was felt in nearby towns.
