The Pacific Tsunami Warning Center says the threat of tsunami in the South Pacific has now largely passed. It issued the warning after a magnitude 7.7 earthquake struck southeast of the Loyalty Islands in New Caledonia on Friday.
The center says it hit at a depth of 10 kilometers.
There were reports of tsunami waves up to 61 centimeters high hitting Vanuatu's Tanna island and waves of 3 to 20 centimeters in New Caledonia.
Waves of 11 to 21 centimeters also hit New Zealand's East and North capes.
The warning center says minor sea level fluctuations may continue over the next few hours. It says people near the impacted coastal areas should remain on alert.
