That San Andreas fault is expected to reach a depth of about 20 kilometers which is 12 miles. The fault occurred because hot rock in the depths of the earth to be separated like plastic because of the strength in it. It has been estimated there will be an earthquake California in a greater strength that being called the big one in the area of California, but the time cannot be determined.

Specifically earthquakes are more common due to the movement of tectonic plates. Disaster like a tornado or hurricane happened some spots in the US, but the earthquake also resulted in much loss rate and the victims being the worst in the history of the world.
The new study about San Andreas Fault shows the possibility of the great yet powerful earthquake which will be the massive disaster. San Andreas Fault is an 800-mile meeting point of the North America and Pacific tectonic plate. Earthquake California is feared natural disaster in the US up to now. The installment of earthquake warning system is known to have been covering the whole US. Besides, the US government will be actively educate people in preparing the natural disaster.
