How fast does a blast wave from a nuke travel?
Nice question, Zack.Yes the velocity of the blast depends upon the size of the nuclear weapon which is measured according to it’s energy content in kiloton or Kt.The real drama there is, the velocity at the time of the rising fire ball and after that.At the time when the fireball rises, nearby areas or the areas that are within the affected range of the explosion, the shockwaves would exceed supersonic limits or many times that of speed of sound.After the fireball settles, it becomes similar to the speed of sound which is 330 meter / second. I’d refer you a very nice link that has all details.
