While we can sympathise with victims of earthquake in NZ, could such have 
been minimized or avoided - if buildings are designed to be 
earthquake-proof?
  I believe Japan builds high-rise city structures on rollers, or similar, 
so as to absorb tremors, rather than be shaken down by them.
  "Houses for Habitats"?
  What is the first action re building house or city high-rise?  You dig, to 
create foundations, then anchor rest of the structure firmly to the ground.
   In many cases, this is a good idea; but what if you are prone to floods 
(let buildings rise accordingly), or earthquakes (roll with the tremors), or 
bushfire (have an inner fire-proof core).  Volcano?  Hmm.
   Destruction of cathedral?  Act of God?
(See Voltaire; re the Lisbon earthquake.)
