What difference could a few seconds warning make before a big earthquake hits the Bay Area or somewhere else in California?

Seismologists and safety experts say it could mean the difference between life and death. Trains could be stopped and elevators could open on the next floor before the shaking begins. The technology already exists -- Japan, Mexico and Romania already have warning systems.

Now, California may catch up. Host Tara Siler talks with State Senator Alex Padilla, who on Monday introduced legislation to create a statewide system.

The project could cost up to $80 million. But instead of using state money, Senator Padilla is looking for a public-private partnership or federal funding.
