The California Geologic Survey has published a new map of landslide susceptibility for the entire state of California. It addresses only deep-seated landslides, not shallow slides such as debris flows. The criteria used for developing the map included slope angle, geology, rock shear strength and history of landslides in a given area. You can download the map for free from the California Geologic Survey.

The slow moving landslide that has been moving on the order of several inches per year has begun moving at a faster rate. They predict movement on the order of feet per year. Several houses have already been condemned and torn down with more likely.
