Strike Slip Fault Hanging Wall

Later we will see how faults are often linked to more distributed deformation and how how you define the boundaries of the fault zone can make a difference.

Strike slip fault hanging wall.

Zones of crustal compression. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. The hanging wall occurs above the fault plane and the footwall occurs below it. Zones of crustal compression.

The displacement of layer b shows that this is a thrust fault. True in a reverse fault the hanging wall block moves up relative to the footwall block. No side is consistently the hanging wall or the footwall for the san andreas fault. Block x is the hanging wall.

Hanging wall up footwall down. Moving the hanging wall up an inclined fault requires work to overcome friction on the fault and the downward pull of gravity. The two sides of a non vertical fault are known as the hanging wall and footwall. This terminology comes from mining.

In these faults the fault plane is usually vertical so there is no hanging wall or footwall. The displacement of layer b shows that this is a strike slip fault. When the hanging wall moves horizontally it s a strike slip earthquake. The forces creating these faults are lateral or horizontal carrying the sides past each other.

Hanging wall and footwall. Typically this occurs in the hanging wall for dipping faults but also occurs with strie slip faults. That means someone standing near the fault trace and looking across it would see the far side move to the right or to the left respectively. That is the slip occurs along the strike not up or down the dip.

Strike slip fault also called transcurrent fault wrench fault or lateral fault in geology a fracture in the rocks of earth s crust in which the rock masses slip past one another parallel to the strike the intersection of a rock surface with the surface or another horizontal plane. Shallow focus quakes do less damage than deep focus quakes. If the hanging wall moves to the left the earthquake is called right lateral if it moves to the right it s called a left lateral fault. Normal faults form in response to horizontal tensional stresses that stretch or elongate the rocks.

Block x is the hanging wall. Some parts of it dip east while others dip west. Since the san andreas fault is a strike slip fault which blocks. Rocks on either side move horizontally in opposite directions.
