The Hayward Fault has a strike-slip motion which is when one land mass moves, nearly horizontally in the opposite direction of the other on the surface. This movement causes stress, which results in earthquakes when the earth moves.  However, movement along the Hayward Fault in the Fremont area is "creeping" so small movements (about 5 mm per year) can occur without an earthquake.

The Sailway Drive Offset is the largest offset in Central Park caused by tectonic plate movement along the Hayward Fault. The curb has a dramatic shift of greater than 3 inches caused by a strike-slip fault movement.
