the best way to answer your question is at the time of choosing an area and a property the seller will provide to you a Geological report prepared by specialized companies, in the Gealogical report it will tell you if the property is located in a earthquacke fault zone, a flood area zone, forest fire zone, etc. Meanwhile if you are still not satisfied with the report you can always call the companie who issued the report to have a better understanding about the geological location of the property you are trying to purchase. Also a simple rule of thumb is hight, the higher you are located geographically the more chance you have not to find your property under water, But than again I am not god and do not know how bad the next big one will affect the geographical state of California. There are stipulations that were mentionend in the past that at the time of the big one that San Fransco and all the areas located near the water will go under, that Los Angeles will become an Island and I do not know how much of LA will be submerged. Still poeple knowing those info are buying in Foster City or Redwood Shores, Etc.. simply because all the positive amenities that those communities are offering including resale value. If you are really concerned with this flooding situation. You really need to look at properties located on the hills build on Bed Rocks.
I am myself a Foster City resident/realtor for the past 19 years and was already there at the time of the 1989 hearthquacke and as you know there was no major structural damages reported at the time. I hope this will help you.
