Argentina: Magnitude-5.4 earthquake occurs in Santa Cruz Province Oct. 13

Event

A magnitude-5.4 earthquake occurred in southern Santa Cruz Province, Argentina at around 04:55 Oct. 13. The epicenter was about 320 km (199 miles) north-northwest of Punta Arenas, Chile. The tremor occurred at a depth of about 15 km (9 miles), and light shaking was probably felt throughout southern Santa Cruz Province in Argentina as well as far southern Aysen and northern Magallanes regions in Chile. 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.

Advice

Plan accordingly for aftershocks. Consider vacating multistory buildings if operating in affected areas until authorities confirm their structural integrity. Allow additional time for air and road travel, as aftershocks may prompt brief disruptions. Seek updated information on road conditions before driving in hilly areas in the affected region due to potential landslides.
