- Strike-slip faults
- Fault rupture of the ground generates vibrations-or waves-in the rock that we fell as ground shaking.
- Faults are weaknesses in the rock and therefore earthquakes tend to occur over and over along the same faults.
- Most major faults in the United States, particularly in California, are what are known as strike-slip faults.
- For strike-slip faults, the rupture is nearly vertical and during an earthquake one side slides past the other.
- The San Andreas fault is a strike-slip fault formed where two parts of the earth’s crust (plates) slide past each other.
