Hanging Wall And Footwall Normal Fault

If the hanging wall drops relative to the footwall you have a normal fault.

Hanging wall and footwall normal fault.

Normal dip slip faults are produced by vertical compression as earth s crust lengthens. Any fault plane can be completely described with two measurements. Which fault will see the hanging wall move down relative to the footwall. Its strike and its dip.

When the fault plane is vertical there is no hanging wall or footwall. What is a reverse fault. Normal faults occur in areas undergoing extension stretching. A normal fault occurs when the hanging wall moves relative to the footwall.

With compressional forces the hanging wall moves upward relative to the footwall. The hanging wall slides down relative to the footwall. Where the fault plane is sloping as with normal and reverse faults the upper side is the hanging wall and the lower side is the footwall. This type of fault is referred to as a fault.

Normal fractures in rock with no offset where there has been no motion are called. A type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50 o to 90 o groups of normal faults can produce horst and graben topography or a series of relatively high and low standing fault blocks as seen in areas where the crust is rifting or being pulled apart by plate tectonic activity. Reverse faults occur in areas undergoing compression squishing. If you imagine undoing the motion of a normal fault you will undo the stretching and thus shorten the horizontal distance between two points on either side of the fault.

Two parallel normal faults form. If the hanging wall rises relative to the footwall you have a reverse fault. The hanging wall on the left slides down relative to the footwall. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.

Normal faults are common. A n fault forms when the hanging wall moves down relative to the footwall a. Other articles where normal fault is discussed. The strike is the direction of the fault.

The hanging wall on the right slides down relative to the footwall. Are exactly the opposite of normal faults. An upthrown block between two normal faults dipping away from each other is a horst.
