Would you mind explaining more the fault around the Oakland zoo? I have always wondered about that curve in the freeway, but where exactly is the “shutter”? Is another fault meeting the Hayward fault?
Thanks

There’s a small but excellent example, without any stream, on the fault just south of Dunsmuir House.

Also, a shutter ridge can only exist on a horizontal, strike-slip fault like the Hayward or San Andreas. Most of the world’s faults are dip-slip faults, meaning the sides move up or down.

See the basics of faults here.

thanks for that explanation! so although this feature must be common along every fault, is it only called a shutter ridge when there is a creek/river involved?
