Still not convinced?  Consider this statement from the City of San Mateo: 

"Perhaps the most widely publicized disaster possible in this area is an earthquake. In addition 
to the famous San Andreas fault which runs under Crystal Springs Reservoir, the Bay Area is 
also blessed with two other major earthquake faults. Even though the Hayward and Calaveras 
faults run through the East Bay, an earthquake on any of the three major faults could cause serious
damage in San Mateo. Recently, scientists have discovered that the bay is riddled with minor 
faults. This has led them to increase their estimates of the likelihood of a major quake from 60% 
in the next 30 years to 90%."  [Emphasis added.]
