The real "tornado alley" obviously isn't even in the US.

As noted above:

"On a tornados-per-square mile basis, England holds the record; but their tornados tend to be "wimpy" in comparison to ones elsewhere."

Canada has about as many tornados as the US, but in both cases there's lots of "empty land" where the majority of them do relatively little damage.

Most of the weather systems likely to generate tornados in the US form up in the "tornado alley," usually in the afternoon, and given the average rate at which the systems move, they're likely to spawn tornados in the "Dixie alley" a little east of there in the middle of the night when people aren't paying attention(?) and when visual tracking to get warnings out are virtually useless, so that smaller storms can hurt more people.

The dangers, and the answers (if we ever really find any) depend on lots of different things. If "generalizing" about what you think "everybody" ought to do makes you feel better, that's fine; but you ain't gonna really help many of the rest of us with it.

When a disaster hits, it's usually pretty clear what kinds of things need to be done to help, and we all of course will do what we can. The things that must be done to help in a recovery are amazingly consistent regardless of what caused the damage, so it doesn't matter much what did it.

Tornado proofing all the houses wont' prevent floods. Hurricane proofing them won't keep the mansions in California from sliding into the ocean. We could (maybe) overcome stupidity of there wasn't so dam*ed much of it - - but of course it sells for a good price so people will keep making it.
