Fuzzy Approach to Landslide Susceptibility Zonation

چکیده
The paper addresses a landslide-prone area on Fruška Gora Mt. in NW Serbia. It proposes a model of relative landslide susceptibility based on fuzzy sets. Having a variety of spatial attributes (proven statistically significant) at disposal, as well as present landslide inventory map, we conducted systematic analysis through (i) assigning fuzzy memberships to attribute categories, and (ii) combining the memberships by means of fuzzy operators. The performance defined by Area Under Curve parameter of the Receiver Operating Characteristics curve, led to preference of Frequency Ratio method for assigning memberships, and Fuzzy Gamma Operator for combining those memberships in 2level experimenting configuration. Results are also well related with previous investigations with different approaches.

Landslides are a major geologic hazard with estimated tens of deaths and $1–2 billion in economic losses per year in the US alone. The island of Puerto Rico experiences one or two large events per year, often triggered in steeply sloped areas by prolonged and heavy rainfall. Identifying areas susceptible to landslides thus has great potential value for Puerto Rico and would allow better managem...
