I have lived in earthquake country for 33 years total. I've experienced at least 15 noticeable earthquakes at home. I even experienced the big quake of 1989 at home. It was scary, but not that scary because I was at home. Extra water, food, tools, gas, etc., that's the boring preparation you can do at home.

The big issue for me is being prepared while away from home. For example, what do I do if the bridge I'm on collapses 100 yards in front of me? What do I do if I'm in an open field and there's a big quake?

There are so many scenarios that can happen away from home that are more likely to put me into a truly dire survival situation. I definitely can appreciate the effort of the original poster!
