The Tonga volcanic eruption unleashed explosive forces that dwarfed the power of the Hiroshima atomic bomb, NASA scientists have said, as survivors on January 15 described how the devastating blast "messed up our brains,” Agence France Press (AFP) reported.
The NASA Earth Observatory said the Hunga Tonga-Hunga Ha'apai volcano spewed debris as high as 40 kilometers into the atmosphere during the eruption that triggered huge tsunami waves. It was even heard in Alaska, at 9,000 kilometers.
