A 6.8-magnitude earthquake struck off the Pacific island nation of Tonga, sending panicked residents into the streets at night, but there were no immediate reports of damage or injuries.
Residents in the capital, Nuku'alofa, 195 km southwest of the epicentre, said their homes rattled, and the tremors set off frantic barking of dogs.
"There's no indication of damage right now in this area," said Faleo Vico, the duty Weather Office staffer in Nuku'alofa.
In the town of Ha'apai, on an island 300 km northeast of the capital, resident Lano Fonua said the quake was strong and lasted about 45 seconds.
"Many people went out into the streets as the quake was shaking the area quite a bit. It was really going," he said.
The US Geological Survey said the quake, which struck at 3:32 am (1332 GMT, 8:32 am EST), was 6.8-magnitude and was generated from a depth of 62 km in the ocean. No tsunami was reported.
"I felt the quake myself. It's not the worst that I've felt here, not by a long chalk," Tonga police commander Chris Kelley said.
On September 29, a tsunami spawned by a magnitude-8.3 earthquake killed 34 people in American Samoa, 183 in Samoa and nine in Tonga.
