There was a little bit of good news that came out of yesterday's earthquake.
A few Berkeley scientists were able to get a 10-second warning BEFORE the shaking reached them. That alert came from a prototype of an earthquake early warning system.
Its success yesterday is prompting calls from officials to expanded it to the entire state. We talked about it with our science reporter, Sanden Totten.
