I’ve received several emails about the veracity of the claims made by Mr. Coop.
While some information is goof, take it with a grain of salt and read the following link:
There’s at least three points I’d pay particular attention to.
1) You’ll die if you hide under a desk. False
It depends on mostly two factors a) the kind of building you are in b) the kind of object or piece of furniture you are using.
For a big old, solid wood desk (or metal) , it will most likely protect you from a wood frame building roof. That’s why its important to notice if there’s a bunch of floors in top of you or not. Cement is heavier and will crush you in most cases.
2) 6) Almost everyone who gets under a doorway when buildings collapse is
killed. How? If you stand under a doorway and the doorjamb falls
forward or backward you will be crushed by the ceiling above. If the
door jam falls sideways you will be cut in half by the doorway. In
either case, you will be killed!False.
Maybe this is the most questionable part about Mr. Coop’s claims, which shows a lack of understanding of structures.
Again, it depends a lot and luck does have a role. But structurally speaking, you are very much hiding “inside” a wall. This means that the center and the sides of the upper floor or roof will collapse away from it and you have a structure around you. It may or may not be a load bearing wall. But if we’re talking typical stick frame, it’s a good place to be in, specially if compared to other places.
I can see the wisdom in staying in fetal position next to a structure that is tough enough to resist a roof falling over it, at least leaving enough space to give you a chance to survive. But its very bold to say the least to talk in absolute terms in such a chaotic situation such as a building falling all over you.
7) Never go to the stairs. The stairs have a different 'moment of
frequency (they swing separately from the main part of the building).
I really don’t understand what he’s trying to say here. You cant make such a claim because buildings are all different and generally speaking, stairs are one of the toughest parts of a building. After all, that’s where people will be going and running down to evacuate the building!
Architects and designers take that into account, its also designed so that, if there’s a fire, people wont suffocate to death. Its probably the most resistant part of the building.
Of course if a 9.3 quake hits and all goes to hell and everything crumbles you’re dead anyway, but he’s making it sound as if stairs are some sort of death traps when they are not.
I just wanted to point these things out guys.
