The Hayward Fault Exposed! An Interpretive Viewing and Educational Exhibit

Saturday, July 01, 2006 - Tuesday, October 31, 2006

Sat - Sun: 10AM - 3PM


See for yourself what an earthquake fault looks like below ground!


Update: The exhibit is now closed, but a permanent exhibit is a possibility. More information »

The exhibit gives you the opportunity to descend a staircase 14 feet and see the Hayward Fault at eye-level. There are also many poster displays providing information on earthquake science and preparedness.

If one prefers not to go down stairs into the trench, the fault can also be viewed from ground level. The exhibit is wheelchair accessible around the top of the trench.

Surrounding the trench are educational displays providing information about earthquakes, faults, and preparedness. The American Red Cross, BART, Association of Bay Area Governments, California Geological Survey, the U.S. Geological Survey, and many other organizations have material on display. A docent is present to answer questions when open.


The trench site is located in Fremont, CA.
