Samoa: Magnitude-5.0 offshore earthquake occurs in South Pacific Ocean at around 08:02 WST Feb. 1

Event

A magnitude-5.0 earthquake occurred southwest of Samoa at around 08:02 WST Feb. 1. The epicenter was approximately 75 km (47 miles) east-northeast of Hihifo, Tonga. The tremor occurred at a depth of about 43 km (27 miles), and weak shaking was probably felt in parts of the western Samoa region. There have been no initial reports of damage or casualties as a result of the earthquake; 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.

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.
