Earthquake in San Francisco?

San Francisco has improved their building code by quite a bit ever since the last couple of quakes, do you guys think that if there is (when there is) another major one most of the buildings and houses will hold up pretty well? I heard that in the 6.9 1989 quake not many buildings and houses collapsed within the city. Does anyone have any knowledge about this and perhaps a few tips to keep your home a safer place? I don't mean about things, they are bound to break but I mean about having somewhere where you can keep yourself safe. Thanks a bunch, yes I am terrified.
