Chile: Magnitude-5.0 earthquake occurs in northeastern Antofagasta Region at around 02:38 Oct. 25

A magnitude-5.0 earthquake occurred in northeastern Antofagasta Region, Chile, at around 02:38 Oct. 25. The epicenter was about 64 km (40 miles) south-southwest of Ollague, Chile. The tremor occurred at a depth of about 127 km (79 miles), and light shaking was probably felt in northern Antofagasta and southern and central Tarapaca regions in Chile and western Potosi Department in Bolivia. There have been no initial reports of damage or casualties; 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.
