California is an area heavily hit by earthquakes. In recent years, Japan, Chile, Haiti, Indonesia, and others have fallen under the destructive hand of this phenomenon.
Of all California is most often hit by earthquakes, but fortunately most earthquakes are of small magnitude. But nobody knows when the Big one comes, or how devastating will be..
And rightly ask: why civilizations rise in disaster areas, in areas that are frequently hit by floods, drought, pest invasions, tornadoes, earthquakes, cyclones?
