Chile: A magnitude-5.2 earthquake occurs in northeastern Antofagasta Region at around 04:21 May 21

A magnitude-5.2 earthquake occurred in northeastern Antofagasta Region, close to the border with Bolivia, at around 04:21 CLT May 21. The epicenter was about 73 km (45 miles) northeast of Calama. The tremor occurred at a depth of about 73 km (45 miles), and light shaking was probably felt throughout parts of northern and central Antofagasta and southern Tarapaca regions in Chile, western Potosi Department in Bolivia, and far northwestern Jujuy Province in Argentina. There have been no initial reports of damage or casualties due to the earthquake; however, significant damage is unlikely. It could take several hours for authorities to conduct comprehensive damage assessments, especially in remote areas. Light aftershocks are likely over the coming days.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
