10Landslides are the most recurrent natural hazards in the Metropolitan District of Quito 11 (DMQ), affecting sometimes lives but extremely frequently and severely the traffic and 12 associated infrastructure. The present research proposes the calculation of the landslide 13 susceptibility cartographic model in the city of Quito and its main highway, the Simón 14 Bolívar avenue, using the Fuzzy logic and multicriteria evaluation techniques in 15 geographic information systems (GIS). Based on the "Today and the past son key to the 16 future" principle, landslides have been located using aerial photographs and field work. 17Based on the characteristics of historical landslides, photointerpreted and previous 18 studies, the causal factors have been variable such as topography, structural geology, 19 lithology, precipitation, water network, vegetation cover, among others. Each factor has 20 been processed, analyzed and standardized according to its relationship to the occurrence 21 of landslides, by means of a sinusoidal linked function that assigns to each element a 22Nat.
