Argentina, Chile: A magnitude-5.7 earthquake occurs in northern San Juan Province, Argentina, close to the Chile border Sept. 6

A magnitude-5.7 earthquake occurred in northern San Juan province in Argentina, close to the border with Chile, at around 07:12 Sept. 6. The epicenter was about 114 km (71 miles) west of Vinchina, La Rioja Province. The tremor occurred at a depth of about 103 km (64 miles), and light shaking was probably felt throughout parts of western Catamarca, northwestern La Rioja, and northern San Juan provinces in Argentina and central and northern Atacama and northern Coquimbo regions in Chile. There have been no initial reports of damage or casualties as a result of the earthquake, and significant damage is unlikely due to the depth of the tremor. It could take several hours until authorities can 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.
