Walk on the Hayward Fault
in Central Park, Fremont

web version funded by California Earthquake Authority

The Hayward Fault is an offset of the San Andreas Fault system that dominates the landforms of eastern San Francisco Bay.  The relative motion between the North American Plate  (southeast) and the Pacific Plate  (northwest) create stress that releases energy as earthquakes. This slip slide motion is called a transform fault.  The Hayward Fault is within the San Andreas Fault  Boundary Zone between the North American Plate and the Pacific Plate.  The Hayward fault is one of only a few dozen faults in the world that “creeps,” or slowly moves.  Evidence of creep can be found from Pt. Pinole in the north to south Fremont.

 

The movement causes features to be created because of the stress.  Materials such as concrete, asphalt, and wood react differently.  Cracks created by this type of stress have a unique pattern.

 

The Hayward Fault Walk in Central Park highlights different fault features:
