Where do dip slip faults occur?

Where do dip slip faults occur?

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 three types of dip slip faults?

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. Reverse faults accommodate contractional deformation.

What are the two types of dip slip faults?

There are two types of strike-slip and two types of dip-slip fault. The two types of strike- slip fault are right-lateral (or dextral) and left-lateral (or sinistral) while the two types of dip- slip fault are normal and reverse (or thrust) (Figure 7).

What type of stress causes a dip-slip fault?

A strike-slip fault is a dip-slip fault in which the dip of the fault plane is vertical. Strike-slip faults result from shear stresses (figure 15).

What type of fault is dip-slip fault?

Dip-slip faults A normal dip-slip fault occurs when the crust is extended. This type of fault is also often called an extensional fault, and in this situation, the hanging wall moves downward relative to the footwall.

What are the example of dip-slip fault?

Dip-Slip Fault: In geology, a dip-slip fault is any fault in which the earth’s movement is parallel with the dip of the fault plane. For example, a normal fault, reverse fault, or listric fault.

What type of stress would occur at subduction zones?

Compression: When Plates Collide When plates press against each other, one plate’s edge is pressed downward by the compression as the other plate’s edge rides over it. These subduction zones appear as deep ocean trenches, usually facing mountains — the protruding edge of the overriding plate.

How are strike-slip faults created?

The cause of strike-slip fault earthquakes is due to the movement of the two plates against one another and the release of built up strain. As the larger plates are pushed or pulled in different directions they build up strain against the adjacent plate until it finally fails.

Which is the largest subduction earthquake?

The largest recorded megathrust earthquake was the 1960 Valdivia earthquake, estimated magnitude 9.4–9.6, centered off the coast of Chile along the Peru-Chile trench, where the Nazca Plate is subducting under the South American Plate.
