What is the motion that is halfway between a normal fault and a strike-slip fault?
Oblique-slip faulting suggests both dip-slip faulting and strike-slip faulting. It is caused by a combination of shearing and tension or compressional forces. Nearly all faults will have some component of both dip-slip (normal or reverse) and strike-slip, so defining a fault as oblique requires both dip and strike components to be measurable and significant.
- Normal and reverse faults move vertically
- Strike-slip faults move horizontally
- Most faults have either a dominant vertical or horizontal component but also possess variations between pure vertical or pure horizontal.
