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.
