Difference Between Hanging Wall And Footwall
Any fault plane can be completely described with two measurements.
Difference between hanging wall and footwall. This steep changes from 50 to 90 degrees. 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. The non moving land is called the footwall. A hanging wall is the overhanging rock unit on the slant that separates the two slabs while the footwall is below the slant.
Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault. The movement along the thrust fault is the foot wall goes down and the hanging wall goes up. Its strike and its dip. Its also called a reverse fault because a normal fault has the foot wall going up and the hanging wall.
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. Moreover the fault surface between footwall and hanging wall dips steeply. The names come about from the. A normal fault is a type of dip slip fault where one side of land moves downward while the other side stays still.
