Couple of questions regarding structures in the "tornado alley":
I see that a lot of homes in the US are timber construction, is this because of the plentiful supply of timber, YEP... if you mean wood construction?the lack of concrete & brick for home construction or is timber the preferred method of construction? Brick doesn't hold up as well as one might think, as well as bricklaying being a dying art in the states. Also many homes in the US have been either or both pre-fab, or lowest bidder built.
Is it mandatory to have a storm shelter/bunker/safe room in homes in "tornado alley"? Not sure on that, but it would make sense.
Short of an areodynamicly designed dome building made of poured steel reinforced concrete, steel blast doors, and with earthen burms all the way around it - anything else is a sitting target for a tornado.
What gets me is that it seems every 4th one misses the trailer parks? So it would make sense not to live in anything that showed up on wheels.
