Strike Slip Fault Hanging Wall

High angle 45 or more dip thrust fault.

Strike slip fault hanging wall. Block x is the 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. The displacement of layer b shows that this is a strike slip fault. Hanging wall up footwall down.

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. Shallow focus quakes do less damage than deep focus quakes. No side is consistently the hanging wall or the footwall for the san andreas fault. When the hanging wall moves horizontally it s a strike slip earthquake.

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. The forces creating these faults are lateral or horizontal carrying the sides past each other. Rocks on either side move horizontally in opposite directions.

Since the san andreas fault is a strike slip fault which blocks. Block x is the hanging wall. The displacement of layer b shows that this is a thrust fault. 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. The two sides of a non vertical fault are known as the hanging wall and footwall. Normal faults form in response to horizontal tensional stresses that stretch or elongate the rocks. Moving the hanging wall up an inclined fault requires work to overcome friction on the fault and the downward pull of gravity.

In these faults the fault plane is usually vertical so there is no hanging wall or footwall. This terminology comes from mining. Some parts of it dip east while others dip west. Identify the true statement.

Hanging wall and footwall. True in a reverse fault the hanging wall block moves up relative to the footwall block. Zones of crustal compression. The hanging wall occurs above the fault plane and the footwall occurs below it.

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.
