It comes after a magnitude 6.4 quake struck in the same area, 74km east of the Loyalty Islands in New Caledonia earlier on Monday.
The natural disaster was initially reported at a magnitude of 7.3 when it struck at 10.44pm on Sunday local time (5.44pm EST) 51 miles east of New Caledonia's Loyalty Islands, just hours after a 6.7 quake struck the same area earlier that day.
Tsunami warning and advisory were issued in the region by The Pacific Tsunami Warning Center.

The PTWC has warned of "hazardous tsunami waves" possible for coasts within 300 km of the epicenter, which puts the Loyalty Islands archipelago, with a population of over 17,000, within range.

"Minor sea level fluctuations.may continue over the next few hours", a statement from the agency said.
Australia and New Zealand do not face any tsunami threats, authorities say.
