A 2004 map showing every Richter magnitude 1.5 to 7 earthquake in the Bay Area (67, 750 of them) from 1970 to 2003 is at: http://pubs.usgs.gov/sim/2004/2848/

Start with — HAZARD VIEWER but note that it has said: “Note that due to the complexity of the maps, each layer may take some time to load.”
You can find detailed maps (with zoom in capability) of potential road closures, risk of liqufaction and flooding (including if a local dam fails during a quake), such as this map of potential Bay Area road closures after a San Andreas fault 7.2 quake,
Especially useful
–On Shaky Ground– Ground shaking hazard maps for Bay Area cities,
–Preparing for Traffic– maps and safety tips for driving in traffic after disasters
— Hazmat Incidents and Dam Failure– click on the links that take you to dam failure and see if your home could be flooded after a quake
You can type in an address and see (not completely accurately, but roughly) where flooding will occur during/after a Tsanami at:

Did You Feel It? is a website where you can look to see if that really was an earthquake you felt, and where you can report one. You select from regions: California, Alaska, Hawaii, Western Mountain, Pacific Northwest, Northeast, Central US, Puerto Rico & US Territories, and Other countries.
The site says: “This is a U.S. Geological Survey project to collect information about ground shaking following significant earthquakes. You can help us by filling out a questionnaire for each earthquake you feel. A Community Internet Intensity Map will be made and updated every few minutes following a major earthquake. At first only a few ZIP codes will have intensities assigned, but over time others will be assigned as data comes in. Check back often and watch the maps change!”

An earthquake early warning alarm system could give people seconds to ten of seconds warning of a major quake. Transit trains could be stopped, fire and ambulance services alerted, and warnings could be sent to home computers and cell phones in the region. Traffic lights could all be made to turn red, stopping traffic before a bridge or a busy intersection. Nuclear power plants could stop operations and refineries could isolate tanks and vulnerable pipelines. People could duck, cover and hold on instead of being knocked off their feet.
Yes, there could be false alarms, but practice at getting under a desk is worthwhile.
