California's drought woes may have dominated recent news, but the 6.8-magnitude earthquake off the coast of Eureka on Sunday was a reminder of another lurking natural threat. In this segment, we'll talk about all things seismic with quake experts John Dvorak and David Schwartz. Dvorak's book "Earthquake Storms" examines the history of the San Andreas Fault, the narrow break in the earth's crust which stretches more than 800 miles from Northern to Southern California.
