New Research shows that a drying lake in Southern California could be the reason we haven't seen a major earthquake on the San Andreas fault down there. 

Researchers in San Diego say that the southern portion of the fault has historically been the quietest section in terms of earthquakes but also that that may not be such a good thing.

For more on this, Brett Burkhart and Patti Reising spoke with Ryley Hill, lead author of the study.
