Chile: Magnitude-5.0 offshore earthquake occurs off the coast of Valparaiso Region at around 03:50 Sept. 5

Event

A magnitude-5.0 offshore earthquake occurred off the coast of the Valparaiso Region at around 03:50 Sept. 5. The epicenter was about 63 km (39 miles) west of Cartagena. The tremor occurred at a depth of about 10 km (6 miles) and was preceded by a magnitude 4.9 quake in the same region. Light shaking was probably felt throughout parts of southern Coquimbo, northern Maule, Metropolitan, O'Higgins, and Valparaiso regions, Chile, and far western Mendoza and far southwestern San Juan provinces, Argentina. 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

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