Chile, Peru: Magnitude-5.1 offshore earthquake occurs off far northern Chile Feb. 20

Event

A magnitude-5.6 earthquake occurred west of far northern Arica and Parinacota regions in Chile at around 06:58 Feb. 20. The epicenter was about 97 km (60 miles) west of Arica, Chile. The tremor occurred at a depth of about 30 km (19 miles), and light shaking was probably felt throughout Arica and Parinacota and northwestern Tarapaca regions in Chile as well as southern Moquegua and Tacna regions in Peru. There have been no initial reports of damage or casualties as a result of the earthquake; 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. 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.

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.
