What Are The 4 Types Of Fault?

What type of fault is the San Andreas Fault?

strike-slip faultwhat type of fault is the san andreas.

A San Andreas earthquake would be classified as occurring on a strike-slip fault.

Strike-slip faults are found along boundaries of tectonic plates sliding past each other..

What is an example of a normal fault?

A normal fault is a fault in which the hanging wall moves down relative to the footwall. … An example of a normal fault is the infamous San Andreas Fault in California. The opposite is a reverse fault, in which the hanging wall moves up instead of down. A normal fault is a result of the earth’s crust spreading apart.

How do you identify a normal fault?

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.

Do normal faults cause earthquakes?

Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. … The fault surface can be vertical, horizontal, or at some angle to the surface of the earth.

What is the most dangerous type of fault?

Strike slip faults also tend to produce quakes with a maximum magnitude around 8. The largest earthquakes however happen on subduction zone faults (also called megathrust faults); the largest recorded quake on those faults had a magnitude of 9.5.

What are the 3 types of faults?

There are three kinds of faults: strike-slip, normal and thrust (reverse) faults, said Nicholas van der Elst, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory in Palisades, New York.

What are normal faults caused by?

Tensional stress, meaning rocks pulling apart from each other, creates a normal fault. With normal faults, the hanging wall and footwall are pulled apart from each other, and the hanging wall drops down relative to the footwall.

What is a normal fault?

normal fault – a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

What are the types of fault?

There are three different types of faults: Normal, Reverse, and Transcurrent (Strike-Slip).Normal faults form when the hanging wall drops down. … Reverse faults form when the hanging wall moves up. … Transcurrent or Strike-slip faults have walls that move sideways, not up or down.
