Faults

 

  1. THE NORTH AMERICAN PLATE
    The North American Plate is a large land mass that is slowly moving towards the west as depicted in the image above. Everything to the north and east of the San Andreas Fault on the map is on the North American Plate.

  2. THE ANTELOPE VALLEY
    The Antelope valley is located between the two longest faults in California the San Andreas fault, which is a right lateral strike slip fault, to the south of the Antelope Valley and the Garlock Fault, which is a left lateral strike slip fault, to the north. The San Andreas is the Plate boundary between the North American Plate and the Pacific Plate. The pressure of these two colliding plates is causing the Antelope Valley to be “wedged\pushed” eastward. The Garlock Fault is where the Antelope Valley literally “breaks loose” from the North American Plate as it is pushed eastward.

  3. THE PACIFIC PLATE 
    The Pacific Plate (everything south and west of the San Andreas) is slowly moving north. As it moves north it collides with the North American Plate. When this collision occurs the San Gabriel mountains are pushed up like the hood of a wrecked car. When the plate cannot move north any more it “slides” in the direction with the least resistance, which is west. When the Pacific plate has slid around the solid land mass (1,2) it is pushed north once again.
