Don't hide under desks or in doorways. Instead sit NEXT to a big object. This is called a safety triangle? In any case, stuff falls on top

and if you're next to a heavy object, it'll create a slope (open space) and you'll be safe \o/

... wait what? How come the desk doorway thing doesn't apply anymore? That's all they taught in Catholic school

you'll be crushed and/or you'll be trapped and run out of air? triangle thing makes sense though... I was thinking of making a simulation

with graham crackers and something sturdy to put inside like a toy block and see what happens in an "earthquake"... then eat it xD
