Most Faults Occur Where The Earths Crust Is Extended
Earthquakes often occur along faults or breaks in Earth's crust where movements occur. These movements happen when stress builds up along the fault and is released suddenly, causing the rocks to break and generate seismic waves. Earthquakes can range in intensity depending on the magnitude of the movement along the fault.

Fractures in rocks where movement occurs are called faults. These are surfaces along which rocks have broken and moved in response to stress. Faults are commonly found at tectonic plate boundaries and can result in earthquakes when movement happens along them.
A fault is a break between areas of rock where movement occurs. This movement can be horizontal, vertical, or oblique, resulting in earthquakes when the accumulated stress is released. Faults are classified based on the direction of movement, such as normal faults (extensional), reverse faults (compressional), and strike-slip faults (horizontal).

A fracture in rock along which movement occurs is called a fault. faults are caused by stress in the Earth's crust, and can result in earthquakes when the stored energy is released through movement along the fault plane.
A fault with horizontal movement is called a strike-slip fault. This type of fault occurs when the rocks on either side of the fault move horizontally past each other. Examples of strike-slip faults include the San Andreas Fault in California.
The majority of faults occur in the plate boundaries.
Focus
Normal faults are caused by tensional stress, which occurs when the Earth's crust is being pulled apart. This causes the hanging wall to move downward relative to the footwall, resulting in the formation of a normal fault.
A break in the Earth's crust along which there has been some movement is a fault. A fault is considered a planar fracture.
