Detailed explanation-1: -Faults which move along the direction of the dip plane are dip-slip faults and described as either normal or reverse (thrust), depending on their motion. Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral.
Detailed explanation-2: -Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally. If the block opposite an observer looking across the fault moves to the right, the slip style is termed right-lateral; if the block moves to the left, the motion is termed left-lateral.
Detailed explanation-3: -An example of a strike-slip fault is the San Andreas Fault in California. The Anatolian Fault in Turkey and the Alpine Fault in New Zealand are also strike-slip faults.
Detailed explanation-4: -Transform boundaries are faults where two plates slide by each other. Such boundaries are inevitable because of divergent and convergent boundaries. The most common transform boundary is the San Andreas Fault; it’s the longest highly active transform boundary on the surface of the Earth.
Detailed explanation-5: -In a strike-slip fault, the movement of blocks along a fault is horizontal. The fault motion of a strike-slip fault is caused by shearing forces. Other names: transcurrent fault, lateral fault, tear fault or wrench fault. Examples: San Andreas Fault, California; Anatolian Fault, Turkey.
