Somehow it seems to me that these bunkers are pretty useless. How they going to generate power and for how long? The amount of unnecessary lights is huge. Water, food, and other stuff? Even if they make in time to get to the shelter, how long are they going to live inside those vaults?
They said there are one year worth of stuff in the bunker, water treatment system, independent power generation, etc. In the case of emergency, I guess they would turn off all of the unnecessary stuff to save fuel and energy. Perhaps in the case of really deep shit, the military going to seize the whole place...
