pictures coming in on another big story, that serious Earth quake back here at home and napa valley. Families are on alert for aftershokz. There's a video shows what it was like to be home sleeping when the ground started to shake. Cecilia Vega in the quake zone for us tonight. Reporter: The violent shaking sent families running for cover. Surveillance video capturing that moment at 3:20 A.M. Sunday at this music store. Drums fly, the ceiling crumbles, while nearby this baby sleeps through all the jostling. What went through your mind? I thought I was going to die. Reporter: In all, more than 200 people injured, their stories just now emerging like little babyish mail, born just before the shaking started. His parents and hospital nurses hovering over him to keep him safe from falling debris. I think mom and dad were more excited. Reporter: The price tag for damage could top $1 billion. At the most famous vineyards in the world, bottles shattered, barrels burst, winery workers helpless as millions of dollars of wine pour right down the drain. The quake hit so hard it ripped this land in half and it's not over yet. Based on past quakes, scientists say there's a 30% chance another big one could hit this week. The worst quake to hit the bay area in 25 years has many calling for an early warning system. Stop, drop and cover your head. Others calling for an early warning system. When an earthquake happens, the waves that cause damage travel from the epicenter at the speed of sound, but sensors near the epicenter that detect earthquakes can send alerts much faster, at the speed of light. The closer you are to the earthquake, the less time you get because the waves get to you sooner. Reporter: That warning system could give up to 40 seconds of lead time in a quake, enough time to stop a train from leaving a station or to get to a safe place in your home. The warning in Sunday's quake, just ten seconds. I'm not sure if ten seconds of warning makes a whole lot of difference. Reporter: So many people I've spoken to today out here tell me how lucky they feel. This wasn't the big one but they all know it could be coming. Just in the past day alone there have been 74 aftershocks. You can see all of this rubble behind me, Diane. Now that cleanup begins. That's right. And expensive, as you said. Cecilia Vega reporting in.
