that makes sence Solus
however not what I have seen kids taught in earthquake prone area's

Not really a contradiction.
The report I read was about going into collapsed structures and finding those who took cover under something sturdy died.
Both the videos assume the structure you are in will not be collapsing. One even mentions covering your head with a bed pillow. They assume falling pieces of plaster, ceiling tiles, lamps and other objects will be what will hit you, not collapsing structure itself.
If it were me and I was without a doubt, positive that the building would not collapse, I'd hide under something sturdy. If I wasn't that sure, I'd curl up next to it and take the beating from the plaster.
