Evacuations from coastal areas were ordered in New Zealand, New Caledonia and Vanuatu as tsunami waves were observed.
The Hawaii-based Pacific Tsunami Warning Center said:
“Tsunami waves have been observed.”
The Center revealed that ocean gauges had picked up small waves near the Tonga capital Nuku’alofa measuring about three centimetres (1.3 inches).
Tsunami alerts were issued along the western coasts of South America and Central America.
More than 60,000 people reported feeling the quake.
However, later the Pacific Tsunami Warning Center said there is no longer a tsunami threat from this earthquake.
