California: What if the Big One Hits

The Big One in California:

I think a “Big One” will happen somewhere across California and it will cause tremendous destruction
There have been approximately fifteen earthquakes over a magnitude of 4.0 per year in California
Even though buildings are made better and stronger today around the world, and most people know how to react to an earthquake, still there is no way to prevent an earthquake from happening.
California will not crumble into the Pacific Ocean, but many people will lose their lifes, and there will be a large amount of destruction
Many businesses will be hurt by a "Big One" and also the military bases would be hurt
