If you have less than 2 seconds of warning of a nuclear blast while within ~5psi shockwave distance then your warning is probably a very bright light from your window. I'd hope for several minutes of warning via public alerting.
- kqr 4y agoThis goes also for conventional charges and things like the Tunguska event. Since the shockwave -- by equality -- comes simultaneously with the sound, the light will be your advance warning. Unfortunately most people's reaction to a sudden bright light is to go stand by the window to see what it is. This gets you killed at distances that would otherwise be survivable with good probability.
