Devore landslide scarp

I showed pictures of the toe end of the Devore debris flow with the damage in the community of Devore. Here are a few photos of the head end of the landslide – where the debris flow originated.

This hummocky, steep topography is characteristic of landslide regions, and found in the hills above Devore.

Geologists call this feature a “scarp”. It indicates where the landslide originated when the hillside became saturated with rainfall. The added weight and pore pressure of the water overcame the cohesive strength of the hillside, and the hillside failed.
