More than 11,000 people would be killed if a hydrogen bomb hit Mansfield, a computer programme has predicted.
North Korean officials have claimed the country carried out an underground hydrogen bomb test yesterday (Wednesday, January 6).
The computer programme, Nukemap, predicts 11,190 fatalities and 20,980 injuries – if the bomb has a yield of 10 kilotons, as the country claims.
If, in the unlikely event the bomb was dropped in the town centre, the radius of the nuclear fireball would reach a diameter of 200 metres causing fatalities and taking out the town centre, including landmarks such as Mansfield viaduct, the Bentinck memorial and the town hall.
The air blast radius would reach up to 470 metres, stretching out over Mansfield Woodhouse.
The pressure of the blast in this area would cause most buildings to collapse and widespread fatalities.
Radiation would reach almost two kilometres and without medical treatment, there could be between 50 per cent and 90 per cent mortality from acute effects alone.
Dying would take between several hours and several weeks and people more than two kilometres away would suffer third degree burns.
