I used it in California. I still have it and it's still good. What I have is called “Quake Hold!” I probably got it at a home improvement store. The label says the company is called Trevco in California, 818-301-0891. http://quakehold.com/
Museum putty is a good idea. I heard about people in California using it because of the earthquakes. You are right about a solid falling when the door opens on the curio cabinet. It has happened to me too. Where can you get museum putty?
