Earthquake Insurance

Who buy earthquake Insurance? Is it advisable to do so?
I have a bad taste in mouth on earthquake Insurance, given the experiences I had during the Northridge earthquake. I'll try to keep him out of this conversation. Historically, California a large earthquake every 15-25 years or more. Consequently, those affected with damage and death home to find some kind of action by FEMA, Red Cross gifts and / or other charities or organizations. The coup earthquake Insurance typically used for all previous payments have been exhausted anyway. In my opinion the best thing to do is maintain the same risk. A can eathquake destroy everything and not really different, a war that is not covered as standard. Frankly, if I was worried about the earthquake, I move to Florida.
