Chelyabinsk Shockwave


Stolen from The Lexicans.

That’s from a roughly 500kt equivalent at an altitude of 25 miles or so.  I’m not a physicist. Do blast shockwaves fall under the inverse square rule?

It’s a good thing, and pure luck, that this didn’t actually smite Chelyabinsk right off the map.

  1. Intuition tells me it follow some sort of inverse square relationship since the area of the shockwave increases with the square of the radius. What other factors would enter in I’m not sure. The shock would fall off fairly rapidly. But, when it starts really, really big, it may be only real big by the time it get to you and that may still be a serious problem. I would think it would propagate sin similar fashion to teh shockwave from explosives. The only difference is that the wave is propagated in the thin air in the upper atmosphere into the thicker air lower, so I’m sure it would go further than, say, the wave from the detonation of explosives at the same elevation where you are.
