NUKU’ALOFA, Tonga, Jan. 15, 2022 (Gephardt Daily) — The eruption of a massive underwater volcano in the South Pacific sent a tsunami wave crashing into Tonga’s largest island Saturday, while triggering tsunami alerts across the region.
The eruption of the Hunga Tonga-Hunga Ha’apai volcano, about 40 miles north of Tonga’s capital of Nuku’alofa, was captured by satellites about 5:26 p.m. local time in a stunning display of power which was heard as far away as New Zealand and Australia.
The sound of the blast described as rolling thunder was also reported in Fiji.
While damage assessments are still being made video posted on social media shows the tsunami as it reaches the Tongan shore and pushes its way through the capital city, flooding streets, homes and other structures.
A wall of water also inundated the Palace Grounds, forcing Tonga’s King Tupou VI to evacuate.

The initial eruption lasted about eight minutes, but how long the volcanic activity will continue is unknown. Volcanic activity in the region often lasts for weeks or longer.
The blast sent a plume of ash and smoke over 12,000 feet high, impacting the weather throughout the region. Ash, mixed with rain, was reportedly falling across Tonga shortly after the eruption.
