Oh? NZ is on a major fault line. They do plan by having earthquake 
rated buildings. Of course things will fail, but it doesn't mean you 
ignore the environmental conditions in which you are designing a 
system. You do guard against the possibilities, but you may not guard 
for 100% infallibility. Even though a risk may be remote, if it is 
catastrophic should it occur, you better be aware of it and mitigate 
as best as possible.

Our truest response to the irrationality of the world is to paint or
