If The Hanging Wall Moves Down Relative To The Footwall, It Is Called Which Kind Of Fault?

In what type of fault does the hanging wall move up relative to the footwall at an angle of less than 45 degrees?

Reverse dip-slip faults result from horizontal compressional forces caused by a shortening, or contraction, of Earth’s crust. The hanging wall moves up and over the footwall. Thrust faults are reverse faults that dip less than 45°.

What type of fault occurs when the hanging wall moves up relative to the footwall quizlet?

2) Reverse Fault– if the hanging wall moves up relative to the footwall, the fault is called a reverse fault.

When the footwall block moves up relative to the hanging wall block it is called a ___?

E.S. Chapter 11 Sections 1-4

Term Definition
tensional stress Normal faults are caused by _________ _____
reverse A _______ fault is a fault in which the hanging wall block moves up relative to a footwall block
thrust ______ faults are reverse faults with dips of less than 45°

What are the three types of faults?

Different types of faults include: normal (extensional) faults; reverse or thrust (compressional) faults; and strike-slip (shearing) faults.

What is fault creep?

In geology, aseismic creep or fault creep is measurable surface displacement along a fault in the absence of notable earthquakes. An aseismic creep exists along the Calaveras fault in Hollister, California.

When a fault is expressed at the surface it is called a?

When a fault is expressed at the surface, it is called a. fault scarp. The name of the site where slippage begins and earthquake waves radiate outward is called the. hypocenter.

What type of fault does stress cause?

In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults.

When most of the movement along a fault is horizontal?

Figure 2. If movement along a fault is horizontal, the fault is called a strike-slip fault. If the rock mass above an inclined fault plane moves down, the fault is referred to as a normal fault.

What is the difference between footwall and hanging wall?

The FOOT WALL BLOCK is the block which would be under the feet of a person standing in a tunnel on the fault plane. The HANGING WALL BLOCK would then be hanging overhead. The UPTHROWN SIDE of the fault is the side on which the movement has been up relative to the other side.

What do you call the block that moves up relative to the other?

A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake – or may occur slowly, in the form of creep.

What happens when bending of rocks along fault becomes too much?

If a rock bends and stays bent after stress is released, it is said to undergo plastic behavior. A combination of elastic and brittle behavior causes earthquakes. Rocks get bent in an elastic fashion until they reach their limit, then they break in brittle fashion.

What are the 2 most common types of dip slip faults?

There are two types of inclined dip slip faults. In Normal faults the hanging wall in moving downward relatively to the footwall. Normal faults accommodate extensional deformation. In reverse faults, the hanging wall in moving upward relatively to the footwall.

What are 4 types of faults?

There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall.

What does a normal fault look like?

Normal faults create space. These faults may look like large trenches or small cracks in the Earth’s surface. The fault scarp may be visible in these faults as the hanging wall slips below the footwall. In a flat area, a normal fault looks like a step or offset rock (the fault scarp).
