Argentina: A magnitude-5.4 earthquake occurs in western Jujuy Province at around 23:36 ART Jan. 20

A magnitude-5.4 earthquake occurred in western Jujuy Province close to the border with Chile at around 23:36 ART Jan. 20. The epicenter was about 102 km (63 miles) north-northwest of San Antonio de los Cobres, Salta Province. The tremor occurred at a depth of about 206 km (128 miles), and light shaking was probably felt throughout parts of northwestern Argentina, northeastern Chile, and far southern Bolivia. 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.
