The Tonga eruption is potentially 15,000 times more explosive than the atomic bombs which the US dropped on Hiroshima in Japan in August 1945 which it estimated would yield 15 kilotons of energy (15.000 tons).
‘The blast released hundreds of times the equivalent mechanical energy of the Hiroshima nuclear explosion,’ s nuclear blast,’ NASA said in a statement.
‘This is a preliminary estimate, but we think the amount of energy released by the eruption was equivalent to somewhere between 4 to 18 megatons of TNT,’ said Jim Garvin, chief scientist at NASA’ s Goddard Space Flight Center.
Tsunami warnings extended as far away as the US Pacific Coast and the detonation played out as far away as Alaska.
