Experts within the field of nuclear weaponry are expressing serious doubt over North Koreas claim that the rogue nation has successfully completed a hydrogen bomb test, going further to state they believe that the seismic activity following the experiment proves their theory.
According to both scientists and intelligence agencies, the blast from the alleged H-Bomb was far too small for even a failed test, leading experts to believe that North Korea has tested a different type of weapon while attempting to disguise it as a hydrogen bomb.
As opposed to the atomic bomb, like the one dropped on Hiroshima in 1945, a hydrogen device can be up to 1,000 times more powerful.
However, South Koreas spy agency said the blast from North Koreas device produced an explosive yield of just six kilotons, even smaller than Hiroshimas.
South Korean lawmaker Lee Cheol Woo, who sits on the parliaments intelligence committee, says the agency told him that even a failed hydrogen bomb detonation typically yields tens of kilotons.
While an atomic bomb uses just nuclear fission (the splitting of atoms), a hydrogen version uses fission as a first-stage detonation to set off a fusion (combining of atoms) reaction, generating temperatures similar to those found at the suns core.
This could mean that North Koreas test was successful at the fission stage, but failed to produce the resulting fusion reaction.
North Korea does have A-bomb technology: its first three nuclear tests, from 2006 to 2013, were devices on roughly the same scale as the ones used on Hiroshima and Nagasaki.
Crispin Rovere, an Australia-based nuclear policy and arms control specialist, said: The seismic data thats been received indicates that the explosion is probably significantly below what one would expect from an H-bomb test.
So initially it seems to be that theyve successfully conducted a nuclear test, but unsuccessfully completed the second-stage hydrogen explosion.
