Its epicenter was located between Quillagua and Tocopilla, affecting the Tarapacá and the Antofagasta regions in northern Chile.

In this region, known as the Peru-Chile subduction zone, the Nazca plate thrusts beneath South America at a rate of approximately 79 mm/year in an east-north-east direction.

In 1995, a magnitude 8.0 earthquake occurred in the same subduction zone approximately 200 km further south of the November 14th event.

There were also reports of widespread power outages in the region, including the cities of Antofagasta, Calama and Arica.
