(I'm saying that having once been a fire officer in a jurisdiction which had
a wood-frame enclosed shopping mall!!!)
Chelsea, MA had the same fear that our town fathers had, that strong codes
would drive away tax-paying business. Those weak-code businesses burned down
pretty much all of Chelsea (incidentally destroying the tax base).
But what's obvious from Chch is that the codes might not save us.
Case in point: The Hotel Grand Chancellor, totally "earthquake-proof" by the
latest codes, jumped one meter in the 6.3, then jumped another meter in one
of the later shocks. Really! What building can withstand that?

Not exactly on topic but codes related is the emerging story that the fire
that recently claimed an LA Firefighter was in a building that may have
seriously been built substantially sub code.
His first Grandchild was born the day after he died.
