Chile: Magnitude-5.7 earthquake occurs in Antofagasta Region at around 07:19 April 20

Event

A magnitude-5.7 earthquake occurred in Antofagasta Region, Chile, at around 07:19 April 20. The epicenter was approximately 2 km (1.2 miles) south of San Pedro de Atacama, Antofagasta Region. The tremor occurred at a depth of about 97 km (60 miles), and light shaking was probably felt throughout Antofagasta in Chile, far southwestern Potosi Department in Bolivia, and far western Jujuy and Salta provinces in Argentina. There have been no initial reports of damage or casualties as a result of the earthquake; significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are possible 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.
