<P> In a normal fault , the hanging wall moves downward , relative to the footwall . A downthrown block between two normal faults dipping towards each other is a graben . An upthrown block between two normal faults dipping away from each other is a horst . Low - angle normal faults with regional tectonic significance may be designated detachment faults . </P>
