Can result in a tsunami as the Earth is pushed up against the ocean during an earthquake.

One side of the fault drops down relative to the other side of the fault during an earthquake.

The opposite side of the fault drops down from what at a normal fault during an earthquake.

Rather than moving up and down, the earth slides side-to-side along the fault line.

Extension Fault

Extension faults occur in areas where the earth's crust has been stretched by other fault lines ripping it apart, sometimes creating new normal faults.
