Still, everybody is going to get wet! But really, these 'megaquakes' don't really put out much ground motion, since they rupture rather slowly. Decent construction can handle that. It's just that all those luxury condos might get their bottom floors wet! So, if I were a zillionaire and could actually buy something in Vancouver on the sea, I would check the foundation (better be rock!), and I would go up a few storeys. Maybe not the top, since I think that's going to throw around a few people!
