In a non-vertical fault (where the fault plane dips), the footwall is the section of the fault that lies under the fault, while the hanging wall lies over the fault.

The names come about from the mining industry because important ore minerals were commonly deposited along fault planes. In a mine along a fault, the miner would be standing on the block lower block and hanging his lantern from the upper block (hence, foot wall and hanging wall).

In perfectly vertical faults, you cannot designate a footwall or a hanging wall.

What is the difference between a hanging wall and a foot wall?

In geology, the hanging wall refers to the rock layer above a fault plane, while the footwall refers to the rock layer below the fault plane. The hanging wall moves downward relative to the footwall in a normal fault, whereas in a reverse fault, the hanging wall moves up relative to the footwall.


Is the hanging wall the same as a footwall?

No


How is the hanging wall different from the footwall?

The hanging wall is the upper block in a fault where movement has occurred, while the footwall is the lower block that has not moved. The hanging wall moves over the footwall in response to stress within the Earth's crust.


Is a hanging wall the same as a footwall?

No, a hanging wall and a footwall are not the same in geology. The hanging wall is the block of rock above a fault line that moves down relative to the footwall, which is the block of rock below the fault line that moves up.


What is the result When a hanging wall of a fault slips down with respect to the footwall?

When the hanging wall of a fault slips down with respect to the footwall, it results in a normal fault. This type of faulting is associated with extensional tectonic forces, where the hanging wall moves downward in relation to the footwall, creating space between the two blocks.


In A Blank Fault The Hanging Wall Moves Up Relative To The Footwall?

In a normal fault, the hanging wall moves down relative to the footwall, whereas in a reverse fault, the hanging wall moves up relative to the footwall.


The hanging wall slides up and down over the footwall is called?

That geological structure is called a normal fault, where the hanging wall moves down relative to the footwall. If the hanging wall slides up and over the footwall, it is known as a reverse fault.


In a hanging fault the hanging wall moves up relative to the footwall?

Is the strike slip fault a hanging wall or a footwall?

A strike-slip fault does not have a hanging wall or footwall because the movement is primarily horizontal, with the two sides sliding past each other horizontally.


How does the hanging wall in a normal fault move in relation to a reverse fault?

In a normal fault, the hanging wall moves downward relative to the footwall, creating extensional forces. In a reverse fault, the hanging wall moves upward relative to the footwall, generating compressional forces.


When the hanging wall moves up relative to the footwall it is a fault.?

Yes, when the hanging wall moves up relative to the footwall along a fault, it is known as a reverse fault. Reverse faults are caused by compressional forces in the Earth's crust, leading to the hanging wall moving up and over the footwall.
