Strike Slip Fault Hanging Wall

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.

Strike slip fault hanging wall.

Zones of crustal compression. Since the san andreas fault is a strike slip fault which blocks. When the hanging wall moves horizontally it s a strike slip earthquake. Typically this occurs in the hanging wall for dipping faults but also occurs with strie slip faults.

Block x is the hanging wall. That is the slip occurs along the strike not up or down the dip. This terminology comes from mining. 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.

When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. The displacement of layer b shows that this is a strike slip fault. 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 faults are either right lateral or left lateral.

Some parts of it dip east while others dip west. Hanging wall and footwall. The two sides of a non vertical fault are known as the hanging wall and footwall. Hanging wall up footwall down.

The displacement of layer b shows that this is a thrust fault. Shallow focus quakes do less damage than deep focus quakes. High angle 45 or more dip thrust fault. Block x is the hanging wall.

Rocks on either side move horizontally in opposite directions. Normal faults form in response to horizontal tensional stresses that stretch or elongate the rocks. Identify the true statement. 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. 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. No side is consistently the hanging wall or the footwall for the san andreas fault. The forces creating these faults are lateral or horizontal carrying the sides past each other.

In these faults the fault plane is usually vertical so there is no hanging wall or footwall.
