Hours before the latest test, North Korean state media published photographs of leader Kim Jong Un inspecting a peanut-shaped device that it said was a hydrogen bomb designed to be loaded on a new ICBM. Such a weapon, with the first stage based on nuclear fission - splitting atoms - and the second on nuclear fusion, produces much more power than traditional atomic bombs, or “pure fission” devices. Suh, a nuclear engineering professor at Seoul National University.Ī hydrogen bomb usually uses a primary atomic bomb to trigger a secondary, much larger explosion. “That scale is to the level where anyone can say (it is) a hydrogen bomb test,” said Kune Y. NORSAR, a Norwegian earthquake monitoring agency, estimated the yield at 120 kilotons, significantly above the 15 kiloton “Little Boy” bomb dropped on Hiroshima and the 20 kiloton “Fat Man” dropped on Nagasaki at the end of World War Two. The detonation produced 10 times more power than the fifth nuclear test a year ago, South Korean and Japanese officials said. Geological Survey at magnitude 6.3 - said there was enough strong evidence to suggest the reclusive state has either developed a hydrogen bomb or was getting very close. North Korea conducted its sixth and most powerful nuclear test on Sunday, which it said was a successful detonation of an advanced hydrogen bomb, technically known as a two-stage thermonuclear device.Īll of North Korea’s six nuclear tests including the one on Sunday have taken place at its underground testing site in Punggye-ri, deep in mountainous terrain, and it is hard to independently verify the claims.īut experts who studied the impact of the earthquake caused by the explosion - measured by the U.S.
