Tonga: A magnitude-5.4 offshore earthquake occurs at around 02:56 April 21
A magnitude-5.4 offshore earthquake occurs in Tonga at around 02:56 April 21. No immediate reports of damage or injuries.
Event
A magnitude-5.4 earthquake occurred at 02:56 April 21. The epicenter was about 120 km (75 miles) north northeast of Nuku'alofa. The tremor occurred at a depth of about 135 km (84 miles), and shaking was probably felt throughout Tonga. There have been no initial reports of damage or casualties due to the earthquake. 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.
