Atomic Bomb Dome (Genbaku Dome)
Severe structural damage to buildings extended about 1 mile from ground zero, making a circle of destruction 2 miles in diameter. The blast sent out a hyper intensified shock wave which travelled at about the speed of sound, turning everyday windows and buildings into shrapnel. At one mile, the force of the blast wave was 5 psi, with enough duration to implode houses and reduce them to kindling.
