I live in Southern California, AKA earthquake country. I have a four post
lift that, like most four post lifts, does not have to be bolted down. One
concern I have, however, is what happens to a car on the lift and a car below
the lift in the case of an earthquake. Seems to me that a moderately strong
earthquake could topple a lift leaving both the top and bottom cars in a bad
state. But, just bolting a lift down would not seem to be enough. Unless the
bolts extended well into a deep footing, I would think a moderately strong
earthquake would pull the bolts out of the ground. Does anyone have any ideas
as to how to earthquake-proof a lift?
