Underwater volcanic eruption in Tonga felt around the world, tsunami waves hit Pacific coast

Eruption of the Tonga volcano: A massive underwater volcanic eruption was recorded in the small island nation of Tonga on January 15, 2022. The event triggered a tsunami warning along the Pacific coast. Tsunami waves have been seen crashing on Tonga’s shores, but the extent of the damage is unclear as the Pacific island nation remains cut off from the world with a downed communications line.

The force of the volcanic eruption was such that tsunami warnings were issued in Japan, Australia, New Zealand, Fiji, Russia, Chile and the United States. Tsunami waves were seen in Amami-Oshima Island, southern Japan, and many other places along the coast on January 16.

The Japan Meteorological Agency has issued tsunami warnings for the Amami Islands and the Tokara island chain in Kagoshima Prefecture. A 120 centimeter tsunami wave was observed at Kominato on Amami-Oshima Island. In addition, tsunami waves of up to 90 centimeters have been observed along the Pacific coast of Japan, from the southern island of Kyushu to the northern island of Hokkaido.

An evacuation order has been issued for at least 230,000 people in eight prefectures across the country. People were asked to stay on high alert and evacuate to higher ground. Russia also issued tsunami warnings as waves of up to 20 centimeters were expected in the Russian Kuril Islands. More than 100 families were also evacuated from Samoan coastal villages.
