20220721 14351800 1.0 TRUE TRUE CSMW_Landslide_Susceptibility_in_California The San Francisco-Pacifica Coast grid map was extracted from the California Geological Survey Map Sheet 58 that covers the entire state of California and originally published in May of 2011. It made use of several data layers such as Landslide Inventory, Geology, Rock Strength and Slope of varying scales and formats. For the statewide analysis of landslide susceptibility, the methodology of Wilson and Keefer (1985) was used in combining the rock strength and slope data layers as implemented by Ponti, el al. (2008) to create classes of landslide susceptibility. These classes express the generalization that on very low slopes, landslide susceptibility is low even in weak materials, and that landslide susceptibility increases with slope and in weak rocks. The extracted grid map is composed of two data layers (Arc GRID Integer): sfcoast_sus- landslide susceptibility (1.16 MB) with cell value from 0 to 10 (low to high) representing susceptibility classes. sfcoast_ls10-existing landslides in digital form (43.3 KB) with cell value of 10 (assigned to the highest susceptibility class by default). Deep-seated Landslides Landslide Susceptibility Landslide Hazard Relative likelihood of deep-seated landsliding based on regional estimates of rock strength and steepness of slopes.
