KCRA: State Sen. Jerry Hill, representing the Southern San Francisco Peninsula, has lived in the Bay Area his entire life. He said that extra lead time can make a huge difference in saving lives. "Before it starts shaking where you are, all of the elevators come to a floor and the doors open, the fire stations, the doors open automatically, before the earth shaking where they are. The rapid transit trains stop, machinery stops," said Hill. "If I'm having by some chance an ophthalmologist performing laser surgery on me, I want to make sure he knows and stops before that shaking begins."
