The center's Twitter account revealed that the earthquake struck some 129 kilometers southwest of the Chilean city of Copiapó. Initial seismograph readings were revised from magnitude 6.3 to magnitude 6.5 within the first hour after the event.
The possibility of the event triggering a tsunami has been ruled out by the Hydrographic and Oceanographic Service of the Chilean Navy.
