Magnitude-5.8 offshore earthquake occurs east of Tonga at around 07:34 TOT Sept. 21. No reports of damage, no tsunami warning issued.
Event
A magnitude-5.8 earthquake occurred in the Pacific Ocean east of Tonga at around 07:34 Sept. 21. The epicenter was about 124 km (77 miles) east-northeast of Ohonua, Tonga. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was likely felt near the epicenter. 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. Officials have not issued any tsunami advisories in response to the earthquake.
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.
