The 6.4 magnitude quake is the latest in a series of recent massive earthquakes to be recorded in the region, which is located along the Pacific Ring of Fire.
No tsunami warning has been issued.
The epicenter of Monday’s quake was located 73 km north of Hihifo in Tonga, 254 km of the Samoan capital, Apia and 326 km west of Pago Pago in American Samoa.
It was recorded at a depth 35.4 km, making it a shallow earthquake, according to the United States Geological Survey.
Vanuatu, also located in the South Pacific, was struck by two large earthquakes during the last 24 hours.
A strong earthquake with a 6.1 magnitude struck off the island nation of Vanuatu on early Monday morning, seismologists said, but there were no reports of damage or casualties. It comes less than a day after a powerful earthquake struck the same area.
A day before a 7.0 magnitude earthquake struck south east of the Vanuatu island of Tanna.
Vanuatu and Tonga are on the so-called “Pacific Ring of Fire,” an arc of fault lines circling the Pacific Basin that is prone to frequent and large earthquakes. Volcanic eruptions also occur frequently in the region.
