The US-based Pacific Tsunami Warning Center said tsunami waves as high as 60 cm were also seen by sea level gauges in Pago Pago, the capital of American Samoa, following volcanic activity in Tonga.

Jesse Tuisinu, a television reporter from Fiji Forest, posted a video on Twitter in which large waves wash ashore with people trying to escape in their cars.

“It is really dark in some parts of Tonga and people are running to safer places after the explosion,” he said.
