Quoted: I've heard an F5 can scour the earth down a couple feet even. |
Not sure about that, but I have seen photos of F5 tracks, and the earth is scrubbed free of grass growth in places. In some cases slab foundations have been moved, lifted and cracked.
We have a good basement shelter for a Tornado, but getting out of it afterwards might be troublesome depending on how many huge piles of rubble we are buried under. |
I am not sure of the "couple of feet" down, but I personally saw the May 3rd '99 F5, and what it did.
Everything that stuck up even a fraction of an inch from the ground... no longer existed.
As for the ground itself, it looked like a plow or gigantic rake had scoured the earth.
Plants, pulled up by their roots, left holes in the ground -- that may give the impression of a "couple of feet" of dirt removal.
