Seismic question:
I've got the standard spare fridge in the garage setup for my cellar (posted somewhere earlier in this thread). I can't imagine it's very earthquake safe - I imagine the top rack getting jostled out of its slot (hooks in the back) and collapsing onto the bottom bottles (the veggie drawer with the lambic should be safe though

) and the door swinging open and the bottles falling out onto the hard concrete and shattering into a million broken dreams. Beyond putting like a welcome mat or something outside the front to prevent anything that might fall from an open door breaking, any suggestions or thoughts on securing the top rack a little better?
PS - here's an old photo of the setup:
