The Language of Landslides
The San Francisco Bay Area has all the ingredients for dangerous landslides: steep hills, lots of rain, and heavy development. Add in an earthquake and you’ve got an even bigger disaster. Geologists study the scars to try to predict the next one.
Why It Matters

- A landscape that is prone to landslides displays clues that can be deciphered by geologists.
- The landslide investigators try to answer these questions:
- Why did the landslide occur where and when it occurred?
- Will another occur in the same spot?
- Is there something we can do to prevent the next one or to minimize damage?
- Landslides created or helped to create many of the canyons in the Bay Area hills.
