In Southern California we accept the fact that certain things are inevitable. In October we have fires, in the winter we have mudslides from the fires(when we have rain that is) . Today we are having an earthquake drill for the mythical "big one" that is going to occur eventually. Of course I've been hearing this "big one" since I was a lad. I believe I know what to do and if I survive I do have an earthquake kit in my car and we have supplies here at home. That's what I have available to me.
I wish there would be a time where earthquakes can be predicted and there has been interesting situations where I've been when there has been earthquakes (in the shower, singing karaoke) but until there is a time I guess it's the same old thing be as prepared as much as you can.
