What is the safe distance from fault line?

Phivolcs now recommends avoiding construction within 5 meters on each side of a fault trace, or a total width of 10 meters. We may call this the ideal "10-meter wide no-build zone" in the vicinity of a fault. Ideally, we should not build in the 10-meter wide no-build zone to avoid the hazard of ground fissure.

What magnitude will the big one be?

Yes. When we refer to "The Big One" we mean a 7.8 magnitude (or higher) quake striking along the southern San Andreas fault. The higher magnitude means it will also last longer than Northridge, but where you are is going to play the largest factor in how this quake feels to you.
