The tectonic plates underneath the earths crust are moving, and these plates crash into, and slide against each other. These places where the plates meet are called fault lines. Since the plates are constantly moving, there is a lot of pressure between the plates, and eventually, it needs to be released in the form of an earthquake.
The majority of faults occur in the plate boundaries.
Most Faults Occur Where The Earths Crust Is Extended

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.
These will form reverse or thrust faults.
Strike slip faults display horizontal or "sideways" deformation.
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.
