FROM THIS EPISODE

The aftershocks are still rumbling after Friday's 5.1 magnitude earthquake centered in La Habra in northeast Orange County. Seismologists say the Puente Hills thrust is "a very dangerous fault." We hear what that could mean. Also, measles and other preventable childhood diseases have been at record lows in California, but fears about vaccination might cause epidemics. We hear about that -- and the complex life of Cesar Chavez.

But, for almost 10 years, it failed to recall Chevy Cobalts and other cars with defective ignition switches linked to at least 13 fatal accidents.  Was there criminal action? We get the background as CEO Mary Barra prepares to defend GM on Capitol Hill starting tomorrow.

Another Reminder for Earthquake Country 14 MIN, 21 SEC

Friday's 5.1 magnitude earthquake was centered in northern Orange County and strong enough to cause a landslide, break water mains and damage buildings. What's the potential for the Puente Hills Fault, which runs from northern Orange County, up through the San Gabriel Valley and right under downtown LA? Is there truth to belief that earthquakes release pent up energy and make new ones less likely?

Cesar Chavez Gets Close-up in a First-of-Its-Kind Biography 10 MIN, 17 SEC

It's a holiday in California in honor of Cesar Chavez -- arguably the most important Latino leader in US history. In the 1960's, he organized poor Mexican farm workers against rich California farmers using boycotts, marches and other forms of nonviolent action. In the process, he inspired a generation of activists for other causes as well as his own. But that's not all there is to the story, as revealed in a new biography, The Crusades of Cesar Chavez, by Miriam Pawel. She also wrote The Union of their Dreams, about the United Farm Workers.
