Chile: Magnitude-5.1 earthquake occurs in Antofagasta Region at around 21:28 April 3

A magnitude-5.1 earthquake occurred in the Antofagasta region of northern Chile at around 21:28 April 3. The epicenter was about 123 km (76 miles) southeast of Antofagasta, Chile. The tremor occurred at a depth of about 80 km (50 miles), and light shaking was likely felt throughout Antofagasta and northern Atacama regions in Chile and far western Salta and far northwestern Catamarca provinces in Argentina. There have been no initial reports of damage or casualties as a result of the earthquake, and significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. 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.
