The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east), causing earthquakes along the fault.Ī new fault forms when the stress on the rock is great enough to cause a fracture, and one wall in the fracture moves relative to the other. Two of these moving plates meet in western California the boundary between them is the San Andreas fault. People also ask, why is the San Andreas Fault so active? In one scenario produced by the United States Geological Survey, researchers found that a big quake along the San Andreas could kill 1,800 people, injure 55,000 and wreak $200 million in damage. Likewise, how has the San Andreas Fault affect humans? Yet in an instant, that crack, the San Andreas fault line, could ruin lives and cripple the national economy. The average rate of movement along the San Andreas Fault is between 30mm and 50mm per year over the last 10 million years. Regarding this, how fast does the San Andreas fault move? It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California.
