WebThis left-lateral oblique-slip fault suggests both normal faulting and strike-slip faulting. It is caused by a combination of shearing and tensional 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.
