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
sing or write, for only in such response do we find truth.
