Another added: "Tonga just experienced an earthquake & the tsunami warning siren has been going off since. "Never knew trauma like I do now," Ten months ago lush green parts of Tonga turned brown and houses were flattened after the massive a volcano eruption on January 15. The enormous explosion - hundreds of times more powerful than the nukes dropped on Hiroshima - ripped through the undersea lava spout of Hunga Tonga–Hunga Haʻapai. With a blast that could seen from space, it triggered tsunamis as high as 90 metres tall which swept across the Pacific. Mega-waves crashed into Tonga, Fiji, American Samoa, Vanuatu, and along the Pacific Rim. Damage was reported as far away as New Zealand, Japan, the United States, the Russian Far East, Chile, and Peru. It was the most powerful volcano eruption since the explosion that ripped apart Krakatoa in 1883.){kind=link}
