Ever stumbled inside one of those carnival fun
houses where the floors are all uneven and the walls are at odd angles?
Ever been groping around in a dark room and put your foot on a stair
step you thought was there -- but wasn't? Ever been on a small boat in
a big storm at sea, with huge waves tossing the boat around like a
small bottle cork? If you answered yes to any of these, or have a good
imagination, then you know a little of what it's like to be surprised
by a large, damaging earthquake.
