Earthquakes

We've had two earthquakes this week. According to the news, they were both 4.5s.
One just happened about an hour ago. (Have I mentioned that I DON'T like earthquakes).
Granted, these are basically tremors. For the most part, they feel like a big truck drove by or a train went by too fast. I think that the reason that I really don't like them, is a fear of the unknown. An earthquake can build and be more powerful. It can be destructive. It is the unknown and potentially dangerous effect that the earthquake may have that terrifies me.
Just thought that I would share that. ^_^
