As a result of the weekend quake in ChCh, I have been reading up on info regarding how to quake proof your tank. Many suggest bolting or strapping the tank and stand to a wall or floor but a structural engineer said he didn't recommend anchoring them to the wall or floor... let them move with everything else. Worst thing is that you will have some water slosh around if the quake is of reasonable size. The higher up you are in a building - the more movement you can expect - e.g. a person living on the 3rd floor will experience greater movement during the same quake than someone living a few floors down. The dynamics of an earthquake are so varying, strapping anything to a wall isn't going to make a difference.
It was also suggesting attaching them to a wall would tend to cause more structural damage than actually save the tank and/or stand from toppling.
Would those who have pics of their damaged tanks, or water mess, please email them to me for use in an article I hope to write for the next AW?
If your tank fell over... Why? (I don't mean you to reply "because of the earthquake" either :roll: ). Was it higher than it was wide? How big was it? Was it a tank and stand combo or a tank sitting on a dresser or something? Did some of your tanks break but not others? Do you know why? What direction were they facing (the quake ran west to east)? Anything else you can think of that would increase our knowledge of what happens in a large quake.
