This is another fault block, but this time the fault is vertical and the layers are tilted gently.  Click and drag the movies, noting the relative movement of the block. Then, read the paragraph below.

This fault is also a dip-slip fault, but since there is no upper or lower block, we cannot call the fault normal or reverse, simply a vertical dip-slip fault. We would just specify which block has moved up or down relative to the other block (in this case the back block has moved up -- we can also say the front block has moved down).
