(Seoul = Yonhap News) Reporter Cha Byeong-seop = Tonga, an island nation in the South Pacific, has issued a tsunami warning due to a nearby submarine volcanic eruption.

According to the AP/AFP news agency on the 15th, the Tongan authorities issued a tsunami warning for the whole country after a volcano erupted 65km north of the capital Nuku’alofa on the same day.

AFP, citing the Australian Meteorological Authority’s Twitter account, said: “A 1.2m high tsunami wave has been seen in Nuku’alofa,” and that Tongan authorities are urging beach and lowland residents to evacuate.

In Tonga, a tsunami warning was issued the day before as a volcanic eruption caused waves of 0.3m high, but the warning was issued again after a few hours.

On this day, which lasted for at least 8 minutes, the volcanic eruption caused gas and ashes to rise several kilometers into the sky, and ‘thunder’ was heard from neighboring Fiji, which was more than 800 kilometers away, AFP reported.

Citing the U.S. Pacific Tsunami Warning Center, Reuters reported that a 0.6m high wave was also observed in American Samoa near Tonga. The center assessed that sea level fluctuations and strong currents could pose a potential hazard to American Samoa beaches.
