A magnitude 6.2 earthquake struck about 219 km (136.1 miles) west-northwest of Pangai, Tonga, on Thursday, the United States Geological Survey (USGS) said.
The earthquake was at a depth of 14.5 km, the USGS said.
The town of Pangai is on the remote island of Lifuka, which is northeast of the capital Nuku'alofa.
There are no reports yet that the earthquake was felt in Tonga or neighbouring Fiji, according to AFP.
From the earthquake's epicentre, the nearest volcano is Kao, which is 154km away, and the nearest habited location is Tongatapu.
It comes almost two weeks after Tonga was devastated by a volcano eruption and tsunami. The eruption on Hunga Tonga–Hunga Ha'apai, an underwater and uninhabited volcanic island, spewed ash into the air on January 14.
The eruption caused tsunamis in Tonga, Fiji, American Samoa, Vanuatu, and along the Pacific rim, including New Zealand, Japan, and the United States.
At least three people were killed and others were injured.
