Chile: Magnitude-5.4 earthquake occurs near Vallenar, Atacama Region, at around 18:49 Oct. 26

A magnitude-5.4 earthquake occurred in southern Atacama Region at around 18:49 Oct. 26. The epicenter was about 46 km (29 miles) east-southeast of Vallenar. The tremor occurred at a depth of about 99 km (62 miles), and light shaking was probably felt in parts of the Atacama and Coquimbo regions of Chile, as well as parts of northwestern 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 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.
