1. Normal Faulting: This occurs when the hanging wall (the block of rock above the fault) moves downwards relative to the footwall (the block of rock below the fault). This type of movement is associated with extensional forces, which stretch the Earth's crust.

2. Reverse Faulting: This occurs when the hanging wall moves upwards relative to the footwall. This type of movement is associated with compressional forces, which squeeze the Earth's crust.

3. Strike-Slip Faulting: This occurs when the two sides of the fault move horizontally past each other. This type of movement is associated with shear forces, which push the Earth's crust in opposite directions.

It's important to note that these are just the three main types of rock movement. There are many other ways that rocks can move during an earthquake, and these movements can be very complex. However, these three basic types provide a good framework for understanding the different ways that earthquakes can happen.
