Today, more than 2.4 million people live close to the fault and are at great risk when the next significant earthquake occurs. If a building was unlucky enough to have been built on the fault, the fault will gradually warp and tear it apart. Technically speaking, the Hayward is a right-lateral strike-slip fault. So despite what non-locals might like to tell you, Hayward is actually a pretty safe city. Just so, when was the last earthquake on the Hayward fault?

Explore the science behind a simulation of a magnitude 7 earthquake on the East Bay's Hayward Fault and learn what it could mean for shaking potential in your area. This means that it shows its everyday action in the form of aseismic creep, the slow, steady sliding of land along the fault’s margin.

To find out more about the potential hazards from an earthquake in the Bay Area, or about the specific area that you live in, the USGS has several great Google Earth maps that show: likeliness of a damaging earthquake, liquefaction likeliness, at risk areas, and potential hazards for our infrastructure. California’s transform fault (a border between the Pacific and North American plates), called the San Andreas Fault, generates a dozen micro-earthquakes every day. The Hayward Fault has ruptured about every 140 years for its previous five large earthquakes. Luckily, facilities near the Hayward fault line have started to take action.
