Does the structure re-center after an earthquake?

A structure re-centers after an earthquake because a restoring force is provided by the rubber. The shaking characteristics also make the structure oscillate at ever-decreasing displacements about its original position as the earthquake motion subsides. The Eel River Bridge in California re-centered after a magnitude 7.0 earthquake to within 1/4 inch of its original position.
