There's a sweet spot where you have a few moments to reflect on the shockwave that is heading your way after you see the bright flash of the explosion (and are probably blinded by that). Far enough away that you can still dive into a corner for protection and survival. Anywhere too close and it won't matter what you do. But there's an appreciable range where the shock wave is going to do significant but potentially survivable damage and where you might have a couple of seconds to do something.
