South Pacific: Magnitude-6.7 earthquake strikes south of Samoa at around 08:24 TOT Dec. 5

Event

A magnitude-6.7 earthquake occurred south of the Samoa Islands at around 08:24 TOT Dec. 5. The epicenter was approximately 108 km (67 miles) northeast of Hihifo, Tonga. The tremor occurred at a depth of about 36 km (22 miles) and light-to-moderate shaking was reported in parts of American Samoa and Samoa. 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. Aftershocks are likely over the coming days. While the event has not prompted any tsunami warning, the Pacific Tsunami Warning Center issued a tsunami advisory for American Samoa indicating that the event could produce strong currents or waves that are hazardous to persons in or very near the water although significant inundation is not anticipated.

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.

Out of an abundance of caution, consider moving away from low-lying coastal areas until local authorities determine that no local tsunami threat exists.
