The two sides of a non vertical fault are known as the hanging wall and footwall.

Faulting hanging wall foot wall.

Because the road lies on two pieces of rock it was broken once the strike slip faulting occurred. The hanging wall slides down relative to the footwall. Other articles where normal fault is discussed. In normal faulting the hanging wall moves downwards in relation to the footwall.

Occurs when the hanging wall moves down relative to the foot wall reverse fault. Normal faults are common. Hanging wall and footwall. The hanging wall occurs above the fault plane and the footwall occurs below it.

The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. This type of faulting is common in areas of compression when the dip angle is shallow a reverse fault is often described as a thrust fault. Encyclopaedia britannica universal images group getty images. I know that for normal fault hanging wall goes down whereas a reverse fault hanging wall goes up.

Faults that move the way you would expect gravity to move them normally are called normal faults. In reverse thrust faulting the hanging wall moves upward in relation to the footwall. In the first picture we can see that strike slip faulting has occurred because there is no hanging wall or foot wall the layers of rock still line up and the road no longer lines up. Hanging wall movement determines the geometric classification of faulting.

A dip slip fault in which the upper block above the fault plane moves up and over the lower block. I always get confused which side is hanging wall and foot wall. Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall. This terminology comes from mining.

They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. A diagram outlining the basics of faulting. Compare the image to the right with the normal fault above. Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault.

We distinguish between dip slip and strike slip hanging wall movements. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. If we hold the foot wall stationary gravity will normally want to pull the hanging wall down right.
