FAULT AND ITS TYPES

FAULT

• A fault is a break in the rock between two blocks, or a group of breaks. Because of faults, the blocks can move around in relation to each other.
• Changes can happen quickly, like an earthquake, or slowly, like creep. Faults range in length from a few millimetres to over 4,000 kilometers.
• Most flaws make the earth's crust move over and over again over time.
• The rock on one side of the crack quickly moves away from the rock on the other side during an earthquake.
• There are many possible slopes for the crack, from flat to steep and everything in between.
• A fault plane is the flat area that shows where a problem is. Where a fault plane hits the ground is called a fault path, which is also called a fault line.
• You can also see a fault on a geology map by a line called a fault trail.

Types of faults

• Based on how the two blocks move, faults are split up into smaller groups.

There are four kinds of faults:

Normal fault

• A dip-slip fault means that the block above the fault has moved below the block below it.
• When something is stretched, this kind of flaw shows up. "What falls when the "hung wall" goes up and the "foot wall" goes down?"

Reverse fault

• Above the fault plane, the top block moves up and over the bottom block.
• A dip-slip fault is the name for this. A lot of this kind of faulting takes place where there is compression.
• When the dip slope is not very steep, a reverse fault is also known as a thrust fault.
• This occurs when the "hanging wall" travels above or below the "foot wall."

Strike-slip fault

• The two blocks can slide past each other because of a bug.
• The San Andreas Fault is on the right side.

Types of strike-slip fault movements

A left-lateral strike-slip fault

• Stand on this kind of strike-slip line and look along its length.
• The block on the left moves towards you, while the block on the right moves away.

Strike-slip fault running from right to left

• Place yourself on the flaw and look all the way along it.
• The block on the right goes towards you, while the block on the left moves away.
• This is a strike-slip line.
