Tonga eruption and tsunami shock the world
Tsunamis and shockwaves hit continents on the other side of the Pacific. The Hunga-Tonga Hunga-Ha'apai (HT-HH) volcano was like a massive shotgun blast from the deep, generating the biggest atmospheric explosion recorded on Earth in more than 100 years. __ Funded by The Nippon Foundation, NIWA and SEA-KIT surveyed over 22,000km2 surrounding the volcano, including mapping 14,000km2 of previously unmapped seafloor as part of The Nippon Foundation GEBCO Seabed 2030 project New Zealand's National Institute for Water and Atmospheric Research (NIWA) has discovered that almost 10km3 of seafloor was displaced – the equivalent to 2.6 million Olympic-sized swimming pools and a third more than initial estimates – with two thirds coming from the summit and the rest from the surrounding flanks. __ Learn more about the survey and the The Nippon Foundation GEBCO Seabed 2030 project: https://niwa.co.nz/news/tonga-eruptio...
