No. An underpass provides no protection from flying debris, the main killer in a tornado. Also the bridge itself can have a wind tunnel effect, so that the winds from the tornado actually speed up when going under it. A ditch is a better option than an overpass, but even then it is only to be used as a last resort.
I would say in a ditch or a hole deep in the ground, DO NOT GO IN AN UNDERPASS,I heard the tornado creates suction in the underpass and will suck you in.
yes
hide in your bathroom! inside your tub will be the best place
The bathroom is generally thought of the as the safest place to hide during a tornado because they normally don't have windows, and tornadoes can easily shatter the glass of them (and therefore cause injuries).
No, the best place to hide in a tornado is a place where there is no or a small amount of windows. Even better, a basement.
Yes. A concrete basement is one of the safest places to be during a tornado.
No. A highway overpass is not a safe place during a tornado at all. An overpass offers almost no protection from flying debris and can actually act as a wind tunnel, causing the wind from a tornado to speed up as it passes through.
they run away from it or hide underground
Yes. Most people who are directly affected by a tornado survive. Consider that the U.S. averages 1200 tornadoes each year resulting in 60 tornado-related deaths. The safest place to hide during a tornado is in a basement or a cellar if you don't have any of those then you should hide in a closet or hallway in the center part of your house on the lowest floor.
Only as a last resort if no other shelter is available.
because unless you have a matress with you to cover yourself, you will die.
The safest place to hide during a tornado is either a basement or a tub with a mattress over top of it. But for an earthquake it is safe to hide inside of your home is in a doorframe or under a desk that is against the wall. The best hiding spot is proably outside and away from trees or buildings. At least outside you won't get crushed by your own house or someone else's.
