A magnitude-6.0 earthquake occurred in northern San Luis Province, close to the border with at around 18:24 Sept. 21. The epicenter was about88 km (55 miles) west-northwest of Villa General Roca, Argentina. The tremor occurred at a depth of about 130 km (81 miles), and shaking was probably felt near the epicenter, as well as light shaking throughout parts of southern La Rioja, San Luis, southern San Juan, northeastern Mandoza, and northwestern Cordoba provinces in Argentina. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. 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.
