Well Dr.Badger, wish that Vancouver, BC area would be better prepared for the big shake that geologists /seismologists have been predicting for past 2 decades.. No one is sure when.

2 weeks ago I was chatting with one of the civil engineers where I work..already they have noticed soil settlement which isn't necessarily just due to softer soil. He did say a suburban area which is delta/floodplain could collapse or get partially underwater when we get the big shake.

The organization I'm with now, is building a 1 km. long road bridge that 4 lanes wide with bike path. They have to install seismic drains...which allows the soil to slide somewhere around the structural foundations when vibration/settlement occurs...but still...that's just such a minor structural detail for baby tremors...

Right there is an all-time high price real estate boom in Vancouver...but you know, one day,...this might go down ..literally...with the shake.
