You can't really prepare for everything. I would even doubt if most of the Amazon higher-ups are thinking much in this direction or are prepared in even the usual ways (2 weeks of food, a barrel of water, and extra batteries level).

We just aren't going to live forever. If its any consolation, you'll (not you in particular :D) probably die in a car accident or a cardiac arrest when you aren't even worried about it.

You can certainly prepare your house for the earthquake and shaking. For one, reinforcing the structure, making sure the ground is under the house is attached to stable, hard rock like granite versus sediment, and very importantly, using wood instead of brick or concrete (look at Bill Gates's Xanadu house - it's not a coincidence that it is completely made out of wood, the best house material for withstanding earthquakes). These people are definitely consulting scientists and engineers and preparing themselves and their family for a potential M9+ event.

The tsunami is more of the problem in the area than the earthquake as far as I understand.
