Strike Slip Fault Hanging Wall

Hanging wall and footwall.

Strike slip fault hanging wall.

The two sides of a non vertical fault are known as the hanging wall and footwall. Rocks on either side move horizontally in opposite directions. Typically this occurs in the hanging wall for dipping faults but also occurs with strie slip faults. Block x is the hanging wall.

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. In a strike slip fault a the hanging wall moves down relative to the footwall b the hanging wall moves up relative to the footwall at the angle of 30 degrees or less c the hanging wall moves up relative to the footwall at an angle of 45 degrees or more d the fault blocks move horizontally in opposite directions. 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. Moving the hanging wall up an inclined fault requires work to overcome friction on the fault and the downward pull of gravity.

Shallow focus quakes do less damage than deep focus quakes. Normal faults form in response to horizontal tensional stresses that stretch or elongate the rocks. That is the slip occurs along the strike not up or down the dip. High angle 45 or more dip thrust fault.

Some parts of it dip east while others dip west. The displacement of layer b shows that this is a strike slip fault. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. Zones of crustal compression.

The forces creating these faults are lateral or horizontal carrying the sides past each other. Block x is the hanging wall. Since the san andreas fault is a strike slip fault which blocks. Zones of crustal compression.

The hanging wall occurs above the fault plane and the footwall occurs below it. Strike slip faults are either right lateral or left lateral. The displacement of layer b shows that this is a thrust fault. No side is consistently the hanging wall or the footwall for the san andreas fault.

Identify the true statement. When the hanging wall moves horizontally it s a strike slip earthquake. Hanging wall up footwall down. 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.

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.
