With its rolling hills and winter storms, the Bay Area has been a landslide hotspot. Now geologists are using new high-tech tools to understand and predict these natural disasters. In this QUEST video produced by KQED, find an explanation of "deep-seated" and "shallow" landslides and examples of Bay Area neighborhoods that have been hit by landslides. Also, take a look at how geologists are tracking and monitoring landslides in the Bay Area.
