Note that most faults that can affect residents are either onshore or just offshore. The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained.In California, the known active surface faults are classified in the 1997 Uniform Building Code as A faults, B faults and C faults. An A fault is the most destructive and a C fault is the least destructive. Only the A and B faults are included in the probabilistic maps. The slip rate and maximum magnitude of earthquakes associated with a fault ...
The earthquakes of California are caused by the movement of huge blocks of the earth's crust- the Pacific and North American plates. The Pacific plate is moving northwest, scraping horizontally past North America at a rate of about 50 millimeters (2 inches) per year. About two-thirds of this movement occurs on the San Andreas fault and some ...
