| Location map of the Hayward Fault Click here to return to Introduction to the Hayward Fault. Fault systems in the San Francisco Bay region are shown on a satellite composite image modified from Google Earth. Faults that have had major earthquakes in historic times (since 1776) are shown in red. Fault that display movement or earthquake history in roughly the last 10,000 years (Holocene Epoch) are shown in orange. Older faults that display evidence of having activity in the last 2 million years (Quaternary Period) are shown in yellow. See Graymer, 2006 for a regional Quaternary fault map of the entire San Francisco Bay region. For a more technical resource guide to the Hayward Fault, see Bryant and Cluet, 2000. |
