Cuz I'm a creep.

No, I do not have an earthquake/emergency kit ready. Yes, I need to make one.

However, this article helps to ease my mind (a little). The Hayward Fault, in East Bay, is c-r-e-e-p-i-n-g along - it moved 4.5mm in the past year. Seismologists think that these small movements help ease fault stress and reduce the chance for a big earthquake. Interesting stuff.
