Well, fingers crossed, huh. Or some engineers out there will be sentenced to hell.
But that building would still stand in my region.
Both floods and droughts are our issues over here, but quakes? Nope, we don't have any, so it would be valid out here.

My understanding is that the Cascadia subduction zone extends from near Eureka in NW Cal (starts at the Mendocino triple junction where the San Andreas ends) all the way to southern BC. It is believed that the Cascadia could generate quakes as large a magnitude 9 every several hundred years. The last such mega-quake is now known from geologic and historic evidence to have occured in the year 1700, 319 years ago. Sometimes the megaquakes are 500 or more years apart, sometimes they are only 200 years apart. The timing is uncertain. Do a web search on "Cascadia megaquake 1700" and all the evidence is there.
