What is unique about a strike slip fault?
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.
How do these faults differ from each other?
Normal faults form when the hanging wall drops down. The forces that create normal faults are pulling the sides apart, or extensional. Reverse faults form when the hanging wall moves up. The forces creating reverse faults are compressional, pushing the sides together.
What are the differences between the three major types of faults?
Three types of faults
- Strike-slip faults indicate rocks are sliding past each other horizontally, with little to no vertical movement.
- Normal faults create space.
- Reverse faults, also called thrust faults, slide one block of crust on top of another.

What is the difference of the three main types of fault in terms of movement and associated stress?
In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults.
What are the different types of fault?
There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.
What type of force causes a strike-slip fault?
shearing forces
The fault motion of a strike-slip fault is caused by shearing forces. If the block on the far side of the fault moves to the left, as shown in this animation, the fault is called left-lateral.
What are 4 different types of faults?
What is oblique slip fault in science?
oblique-slip fault A fault in which the displacements of the strike-slip and dipslip components have very similar magnitudes; fault movement occurs obliquely across the fault surface. A Dictionary of Earth Sciences.
What is fault explain different types of fault?
A fault is a fracture or zone of fractures between two blocks of rock. Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral. Faults which show both dip-slip and strike-slip motion are known as oblique-slip faults.
What are the different types of fault in power system?
There are mainly three types namely line to ground (L-G), line to line (L-L) and double line to ground (LL-G) faults. Line to ground fault (L-G) is most common fault and 65-70 percent of faults are of this type.
What causes strike-slip faults?
The cause of strike-slip fault earthquakes is due to the movement of the two plates against one another and the release of built up strain. As the larger plates are pushed or pulled in different directions they build up strain against the adjacent plate until it finally fails.
What are the two types of strike-slip faults?
Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral.
