It was considered the "Great Earthquake" until 1906. The cracking of the ground along the Hayward Fault was traced about 20 miles (32 km) from San Leandro to Warm Springs in Fremont, although modeling of survey data suggest that the fault moved as far north as Berkeley, and from these data the average amount of horizontal movement along the fault is inferred to be about 6 feet (1.9 meters). How Close to a Fault do You Live? This fault … There are many easy tours you can take to get a closer look at this subterranean beast, as well as maps to find out how close you live to the fault and what seismic hazards—such as landslides or liquefaction—exist near you.

The paleoearthquake histories for nearby faults of the San Francisco Bay region appear to indicate less regular and frequent earthquakes, possibly because most lack the high proportion (40-60%) of aseismic release found on the Hayward fault. They have found that the most recent 5 major earthquakes happened on average every 140 years. Bundled with the map and tour are: 1) photographs showing evidence of creep and other aspects of faulting, 2) locations of creep, 3) locations of exploratory trenches crossing the fault, 4) moving landslides (from InSAR, only available for northern Berkeley Hills), and the kilometer grid used in the published map. The United States Geological Survey has stated that there is an "increasing likelihood" of a major earthquake on this fault zone, with potentially serious resulting damage.
