North Korea’s powerful nuclear test this month may have been even stronger than first reported, equivalent to roughly 17 times the strength of the bomb that destroyed Hiroshima, according to a new analysis by a U.S. monitoring think tank.
North Korea’s Sept. 3 nuclear test, its sixth and biggest, showed how much progress the country has made on its nuclear program.
Estimates of the bomb’s yield, or the amount of energy released by the blast, have ranged from South Korea’s 50 kilotons to Japan’s 160 kilotons, although some analysts have said the 6.3 magnitude of the earthquake caused by the detonation could put it into the “hundreds of kilotons.” This would put it into the realm of thermonuclear weapons, supporting North Korea’s claim that it had tested a hydrogen bomb.
In comparison, the bomb detonated over Hiroshima in 1945 released about 15 kilotons of energy.
The new
analysis by 38 North, run by the U.S.-Korea Institute at the Johns Hopkins School of Advanced International Studies, found North Korea’s test may have been much stronger.
