What Is The Term Used To Refer To A Horizontal Line On An Inclined Fault Surface (or Any Surface)??

Right lateral strike slip fault and transform boundary. What is the term used to refer to a horizontal line on an inclined fault surface (or any surface)? dip.

What type of fault is present when dominant displacement is horizontal and parallel to the trend of the fault surface?

Dip-slip fault where hanging wall block moves UP relative to the footwall block. Dominant displacement is horizontal and parallel to the strike of the fault.

What are the 3 fault types?

There are three main types of fault which can cause earthquakes: normal reverse (thrust) and strike-slip.

What is lateral fault?

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.

What is dip-slip?

Dip-slip faults are inclined fractures where the blocks have mostly shifted vertically. If the rock mass above an inclined fault moves down the fault is termed normal whereas if the rock above the fault moves up the fault is termed reverse.

What do we call a fault in which the movement is horizontal along the strike?

Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral. Faults which show both dip-slip and strike-slip motion are known as oblique-slip faults.

When the dominant displacement is horizontal and parallel to the strike of the fault the fault is said to be?

Strike-Slip Faults

Dominant displacement is horizontal and parallel to the strike of the fault. There is no hanging or footwall block associated with these faults. Instead the two blocks move horizontally past one another. Transform fault – All transform plate boundaries are strike slip faults.

What is a line to line fault?

A line to line fault is one where shortcircuiting occurs between two phases of a system. A line to groung fault is one where shortcircuit occurs between one phase of the system and the earth. A double line to ground fault is one where shortcircuiting occurs between two phases along with the earth at the same time.

What are the 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. A reverse fault is one in which the hanging wall moves up relative to the footwall.

Where are fault lines?

These faults are commonly found in collisions zones where tectonic plates push up mountain ranges such as the Himalayas and the Rocky Mountains. All faults are related to the movement of Earth’s tectonic plates. The biggest faults mark the boundary between two plates.

What is a vertical fault?

Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally. If the block opposite an observer looking across the fault moves to the right the slip style is termed right lateral if the block moves to the left the motion is termed left lateral.

What is a oblique fault?

a fault that runs obliquely to rather than parallel to or perpendicular to the strike of the affected rocks.

What is horst and graben in geography?

Horst and Graben (valley and range) refers to a type of topography created when the earth’s crust is pulled apart. … As the crust is strained in this way normal faults develop and blocks of the crust drop down to form grabens or valleys. The end result of this is a vast landscape of alternating valleys and ridges.

What is focus earthquake?

The focus is the place inside Earth’s crust where an earthquake originates. The point on the Earth’s surface directly above the focus is the epicenter. When energy is released at the focus seismic waves travel outward from that point in all directions.

What’s the definition of footwall?

Definition of footwall

1 : the lower underlying wall of a vein ore deposit or coal seam in a mine. 2 : the lower wall of an inclined fault.

What is a scarp geology?

A fault scarp is a small step or offset on the ground surface where one side of a fault has moved vertically with respect to the other. … They are exhibited either by differential movement and subsequent erosion along an old inactive geologic fault (a sort of old rupture) or by a movement on a recent active fault.

What is a fracture in the crust called when land moves up down or sideways?

fault in geology a planar or gently curved fracture in the rocks of Earth’s crust where compressional or tensional forces cause relative displacement of the rocks on the opposite sides of the fracture. … Faults may be vertical horizontal or inclined at any angle.

What do we call a fault in which hanging wall moves up along the dip with respect to the footwall?

A reverse fault is the opposite of a normal fault—the hanging wall moves up relative to the footwall. Reverse faults indicate compressive shortening of the crust. The dip of a reverse fault is relatively steep greater than 45°.

What do we call a fault in which the hanging wall moves up along the fault with respect to the footwall as pictured )? *?

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.

What refers to the combination of a strike slip and dip slip?

Nearly all faults are a combination of dip-slip and strike-slip faults. The term that is given to faults that have aspects of dip and strike slip faults is oblique-slip faults.

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

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 is the strike direction of the fault?

strike in geology direction of the line formed by the intersection of a fault bed or other planar feature and a horizontal plane. … Dip is the angle at which a planar feature is inclined to the horizontal plane it is measured in a vertical plane perpendicular to the strike of the feature.

What is the expression for fault current in line to ground fault?

The fault impedance of the line is Zf. Since only phase a is connected to ground at the fault phase b and c are open circuited and carries no current i.e fault current is Ia and Ib = 0 Ic = 0. The voltage at the fault point F is Va = Zf Ia.

How do you find the line fault in a line?

What is difference between line to line and line to neutral?

The higher voltage (typically 240V) will be the ‘Line to Line Voltage’. It will be twice the ‘Line to Neutral Voltage’ and is the voltage measured between the two lines. … It will be 1.73x the ‘Line to Neutral Voltage’ and is the voltage between any two line of the three lines.

What is the term used to describe a vertical offset where the fault intersects the ground surface?

Fault scarp. A vertical offset where the fault intersects the ground surface. Stress.

What are the two classified faults?

There are two kinds of strike-slip fault right-lateral and left-lateral. If you stand on one side of a right-lateral fault objects on the other side of the fault appear to move to your right during an earthquake (Figure 3-5a b).

How do you identify a fault line?

To correctly identify a fault you must first figure out which block is the footwall and which is the hanging wall. Then you determine the relative motion between the hanging wall and footwall. Every fault tilted from the vertical has a hanging wall and footwall.

How do fault lines form?

A fault is formed in the Earth’s crust as a brittle response to stress. Generally the movement of the tectonic plates provides the stress and rocks at the surface break in response to this. … If you whack a hand-sample-sized piece of rock with a hammer the cracks and breakages you make are faults.

What is a fault line tectonic plates?

A fault line a break in the Earth’s crust where blocks of crust are moving in different directions will form. Most though not all earthquakes happen along transform boundary fault lines.

Where are the fault lines for earthquakes?

Nearly all earthquakes occur on faults features in the Earth where rocks move past each other. Faults often occur at and near the boundary of large tectonic plates because the plates are moving in different directions.

What is a right lateral fault?

If you were to stand on the fault and look along its length this is a type of strike-slip fault where the right block moves toward you and the left block moves away.

What is horizontal slip?

In a fault the horizontal component of the net slip.

Where do oblique faults occur?

Like longitudinal faults there are several major transverse and oblique faults occurring mainly in the eastern and central parts of the Main Subbasin of Singrauli Basin in the northern part of SVB. These are described below from the east to the west of the basin.
