How swift? It can't be more than 15 seconds between flash of light and shockwave. Staying down for that long in case there's a shockwave seems reasonable. Also

Also, forest fires are not typically sudden flashes of light or found in urban areas. Context matters.
- BerislavLopac 8y agoAccording to the experience in Halifax explosion, a blast wave travels at 1000 m/s; so you get 15 seconds if the blast happens 10 miles away from you.
- SideburnsOfDoom 8y agoGood to know. In the unlikely event etc, I'll give it 20 seconds or so then.
