It is the lengthiest fault zone in the world. The length of it is 800 mils through the US. It crosses the winery, railways, infrastructure and also the water system. The fault line starts from Salton Sea on the south to Cape Mendocino in the north. Every day, there are individuals that do regular activities over it. Even there are 900 road routes across the lines every day.
There is a tendency of people that there will be the big one in the future in relation with the earthquake.
This fault is a result of geological movement of North American plate converges with Pacific plate. It has many small minor branches especially in the southern California. The converge of the North American and the Pacific plate is at an inch.

The 1906 San Francisco earthquake was the worst tragedy in the US caused by this San Andreas fault line. It damaged the entire city and burned with fire from the broken fire pipes.
There may be a recurring moment of the past earthquakes in this fault line that can be a major earthquake in the US.
This fault is still active provided that the North American and the Pacific tectonic plate movement in steady every year.
That is what scary to everyone in the United States. The fault is strike slip which the movement of two tectonic plates past each other.
The label of San Andreas was originated from a dangerous name of Saint Andrew. The past earthquake a century ago may have passed. However, the seismic movement in the fault zone is still active. That may surprise to anyone. Like the earthquake happened in Hayward fault, the geological process of the fault can extend.
The San Andreas fault is really the one fault zone that is significant in North America.
In the Haiti, southern of America, the earthquake happened in a hidden fault line after they did not have any earthquakes since two and half centuries ago. That was a century of geological event of generating tensions. The earthquake was caused by the complex fault zone in the plates edge of Caribbean plate and another micro plate.
However, that of Chile had the most effective code buildings that could stand in the powerful 8.8 magnitude earthquake in 2010.
The US has had a past history of century that the 1906 earthquake struck the US and that was caused by the San Andreas Fault line. It had an extension of fault line on the south as well as on the north.
It can reflect that the San Andreas fault still has a major process of seismic processes under the ground. Even though it had a zero works. Still, in the plate boundary there are proven evident in history of earthquakes. There were in histories that the earthquakes happen in plate boundaries. The example was evident in the Haiti and Chile. The similar case happened in the US where it had the lengthiest of fault line caused by the dynamic movement of the plates. The plates edge still indeed move and accumulate tensions. However, merely prediction of the earthquake can not be done.
