Trace of Hayward Fault Union City
to South Fremont
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
Evidence of creep can be found from Pt. Pinole in the north to
In the Fremont area the Hayward Fault
dissects the city. It goes through the flat land starting
in Warm Springs and goes back into the hills around the
Niles/Union City area. This allows for urban features such as
offset curbs, compression knoll, depressions, cracks, and more.
Pull apart features also causes elongated water features such as
Tule Ponds at Tyson Lagoon and the historic Stivers Lagoon.
