The past few large earthquakes have taught the intelligent people of the world (not here!), that earthquakes happen everywhere at the 1 in 1000 level, and that there should be a minimum seismic capacity for all structures, no matter what the Jaws-like denying officials think.
I divide the world into 3 seismic capacity levels
Level 1 - Smooth Runnings - seismic capacity, expressed by PGV, where there should be no damage, and the place 'rides out' the storm. Nuclear power plants, hospitals, etc should have a high value.
Level 2 - Incapacity - the building is 'taken out', non operational. Very bad for Canada in the winter. Power systems are very low for this.
Level 3 - Pancaking - This won't really happen for Canada, although I do see those cheap condos tipping over.
