Just weeks after Kim Jong-un ordered North Korea’s sixth nuclear test sparking condemnation from the international community, a new graphic — released on the Twitter account of Lassina Zerbo, Executive Secretary of the Comprehensive Nuclear Test Ban Treaty Organisation — shows how a radioactive cloud could spread towards Asia and the U.S. if North Korea carries out a nuclear explosion over the Pacific.
The simulation reveals a possible two-week spread of an ‘atmospheric burst’ that could be unleashed from one of Kim Jong-un’s nuclear weapons.
However, it does not reveal what the yield of the hypothetical explosion would be or what threat such a ‘radio-isotope cloud’ would pose to humans.
Zerbo tweeted that the graphic was a ‘simply a rough simulation of a potential cloud that could carry isotopes!’ and that it had been drawn up following inquiries made to his organization.

North Korea’s sixth nuclear test at the Punggye-ri military site had an expected yield of 250 kilotons, much higher than official estimates. The figure is more than 16 times the size of the 15-kiloton U.S. bomb that destroyed Hiroshima in 1945.
