Like I stated before the State of Hawaii does not have any "Experts",   that were Formally Trained or Experienced with Nuclear (Weapons) Physics and Physiology, Missiles, the U.S. Military Officer Career Field Course Nuclear (Weapons) Physics and Physiology and Schools ended 2000.  Drawing circles on maps is not accurate as Terrain does Matter.   The estimated actual Democratic Republic of North Korea's type and yield is a 10 Mega Ton Thermo Nuclear Warhead and lots of decoys.   As far as "accuracy", the North Koreans obtained 21st Century Technology of Guidance Navigation and Controls (G.N.C.s) from the Chinese, the Circular Error Probability (C.E.P.) being about 50 meters to 100 meters.  Detonation at 200 feet to 500 feet for maximum effect, larger supersonic blast waves.  EMP and EMR would kill all Electronics including other Islands.  Radio, Transceivers, Satellite, Cellphones would not work due to Ionospheric interference from lingering EMR.  100% that saw the blast blind.
