In California, the plate is sliding northwestward along a [[transform boundary]], the [[San Andreas Fault]], toward the subduction zone. At the same time, the [[North American Plate]] is moving southwestward, but relatively southeast along the faultline.  The westward component of the North American Plate's motion results in some compressive force along the San Andreas and its associated faults, thus helping lift the Coast Ranges
, the Diablo Range, and intervening hills.  The Hayward Fault Zone shares the same relative motions of the San Andreas. As with portions of other faults, a large extent of the Hayward Fault trace is formed from a narrow complex zone of deformation which can span hundreds of feet in width.
