NORTH Korea could launch a nuclear strike on Hawaii which would kill 15,000 people with just a 20 minute warning, according to a government file.
Chilling details about the impact of a nuclear strike on Hawaii were detailed in a secret meeting in Honolulu.
Hawaii has been identified by North Korea as a potential target in a map pictured in Kim’s “war room”.
The file details as many as 15,000 people dead, a 20 minute warning, and no evacuation would be attempted.
Residents would warned with a broadcast on TV and radio which is also beamed to mobile phone.
Hawaiians would be urged to take cover, with warning up to 60% of the surviving population could be exposed to radiation.
The details were presented at a meeting in Honolulu, two days after lawmakers met in secret.
It takes the form of a presentation, explaining the threat posed by a nuclear weapon nearly six times more powerful than the one dropped on Hiroshima.
The presentation warns that a nuclear missile couldn’t be intercepted “with absolute certainty”.
A warning statement, which would to be continuously broadcast on radio and TV and beamed to mobiles and pagers, also appears in the presentation.
It states: “The US Pacific Command has detected a missile threat to Hawaii. A missile may impact on land or sea within minutes. This is not a drill.
“If you are indoors, stay indoors. If you are outdoors, seek immediate shelter in a building. Remain indoors well away from windows.
“If you are driving, pull safely to the side of the road and seek shelter in a building or lay flat on the ground. We will announce when the threat has ended.”
Further slides advised families to keep at least two weeks of emergency supplies and gave details on which type of building could best withstand an atomic blast.
The presentation, which carries the seal of the Hawaii Emergency Management Agency, is based on the threat of a 100kiloton bomb detonated at 1,000ft.
However, estimates for the yield of Kim’s H-bomb suggest it used a bomb with up to 250kilotons of explosive power.
Their presentation was marked “official use only” and reportedly showed where North Korea might target for an attack.
Shots have been fired from both sides following a fiery meeting of the UN in New York.
Donald Trump threatened to “totally destroy” North Korea, while Kim’s officials branded him “deranged”.
It emerged today the Pentagon is considering sending a US Navy strike group into North Korean waters.
