Locations of liquefaction features produced during the 1868, 1906 and 1989 earthquakes. Liquefaction features are mapped as points, or scattered along lines. Most of the historical liquefaction has occurred along the region's larger streams: Coyote Creek and Guadalupe River near San Jose. San Francisquito Creek near Palo Alto, and Alameda Creek near Fremont. Filled baylands like in Foster City, were relatively recently constructed, and thus, are likely to be less susceptible to liquefaction than some of the areas around San Francisco and Oakland, where the fill may be more than 100 years old.
