Tonga: Magnitude-5.1 offshore earthquake occurs east of Tonga at around 19:45 June 25

A magnitude-5.1 earthquake occurred in the South Pacific Ocean east of Tonga at around 19:45 June 25. The epicenter was about 126 km (78 miles) east-northeast of Ohonua. The tremor occurred at a depth of about 10 km (6 miles), and weak-to-light shaking was probably felt throughout much of Tonga. There have been no initial reports of damage or casualties; 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.
