Chile: Magnitude-5.3 earthquake occurs in the South Pacific Ocean, Near Tarapaca Region at around 01:01 Oct. 1

A magnitude-5.3 earthquake occurred in the South Pacific Ocean at around 01:01 Oct. 1. The epicenter was approximately 50 km (31 miles) west of Puerto, Tarapaca Region. The tremor occurred at a depth of about 32 km (20 miles), and weak-to-light shaking was probably felt in Tarapaca, Arica and Parinacota, and northern Antofagasta regions. There have been no initial reports of damage or casualties; 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. The event has not prompted any tsunami advisories.

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.
