Chile, Argentina: A magnitude-5.5 earthquake occurs in central Chile, northwestern Argentina at around 21:02 Feb. 4

Event

A magnitude-5.5 earthquake occurred in Coquimbo Region at 21:02 CLST, Feb. 4. The epicenter was about 28 km (17 miles) north of La Serena. The tremor occurred at a depth of about 68 km (42 miles), and light shaking was probably felt throughout parts of Atacama, Coquimbo, and Valparaiso regions, Chile, and parts of La Rioja and San Juan provinces, Argentina. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is possible in La Serena. 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 a regionwide tsunami warning, although minor sea level fluctuations are possible in coastal areas close to the epicenter.

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

Out of an abundance of caution, consider vacating multistory buildings where shaking occurred until authorities confirm their structural integrity. Monitor and plan for aftershocks.
