Is typical in tornado prone areas to require new construction to have safe rooms?

I am under the impression that the only safe place is under ground. My concern with an under ground shelter is being blocked in.

What percentage of houses are destroyed each year by tornadoes?

Yet you demand that every house be tornado proof. Take some time, calculate the odds of that bet, you'll find it greater than winning the lottery.

You can't "retrofit a closet" to make it tornado proof. Just tornado resistant.

Slab houses are cheap.

Tornado shelters are expensive, when most people will never need them.

Well it is true, foundations are built differently in newer buildings to be able to withstand up to a certain point. I am kinda shocked though, that a public institution like those schools did not have a storm shelter or bunker of some sort. Most schools in those areas do.

You would think more homes and buildings would be required to be built with something to shelter people... tornados happen multiple times a year in the Midwest. It's shocking to hear how they had to transport three schools to one school that had an underground shelter.

Where do you live? I also live right on the edge of tornado alley and tornadoes can be pretty frequent here. Last spring we had a horrible storm that knocked out the power for several days. And yeah they are starting to test the sirens again. I think they turn them on the first tuesday of every month here.

Me too. You have homes on the coast being built on stilts. Here you have the same thing. I guess the Midwestern red states produce kids in litters so they don;t mean as much

You kidding they live for disasters and the opportunity to build again. Humans are expendable for those dudes

Once the Obama's weather machine scandal is exposed by fox news,

global warming will be exposed as the hoax that it is.
