Tonga: Magnitude-5.1 offshore earthquake occurs at around 0011 Feb. 4

Event

A magnitude-5.1 earthquake occurred in the South Pacific Ocean in eastern Tonga at 0011 Feb. 4. The epicenter was about 68 km (42 miles) east-southeast of Pangai, Tonga. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt throughout several islands, including Tongatapu, 'Eua, Nomuka, Tofua, Lifuka, and Foa. 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. Ouf of an abundance of caution, consider vacating multistory buildings if operating in areas where shaking occurred.
